<br>
 
The goal of the '''Triennial Budget and Workplan (TWP)''' is to reduce the effort expended on the budget process while improving the effectiveness of the Grand Canyon Monitoring and Research Center (GCMRC), Technical Work Group (TWG), and AMWG. The GCDAMP will develop a TWP the first year of the process. Then, in the second year the GCDAMP would implement the year-two budget and make relatively minor corrections primarily related to changes in CPI and needs at GCMRC and the Bureau of Reclamation. In the third year the GCDAMP would consider minor changes to the year three budget to allow for changes in projects or potential important new starts not envisioned during the development of the triennial budget.

advance general understanding of sediment transport and eddy sandbar dynamics. While the first

−
two efforts are focused on monitoring, the latter effort is focused on improving capacity to

−
predict the effects of dam operations, because management of the Colorado River downstream

−
from Glen Canyon Dam requires that managers balance the objective to achieve fine-sediment

comparing predicted outcomes of different dam operation scenarios, such as has been pursued in

(EIS) process.

The effort to achieve fine-sediment conservation in the Colorado River ecosystem in Marble

−
to the Colorado River from ephemeral tributaries. The challenge of rehabilitating sandbars when
+
|-
−
most of the fine-sediment once supplied to the CRe is now stored in Lake Powell reservoir has
+
|style="color:#000;"|
−
been described in many scientific articles and management documents. More than a decade of
+
−
monitoring and research has demonstrated that eddy sandbars accumulate sand, as well as small
+
−
amounts of clay and silt (hereafter referred to as mud), during short periods of relatively high
+
−
flow, but these same sandbars typically erode during flows that occur in the months to years
+
−
between the high flows requisite for sandbar building. Adoption of the HFE Protocol in 2012
+
−
established a formal procedure whereby seasonal sand and mud (together referred to as fine
+
−
sediment) inflows are measured, and high flows are released from Glen Canyon Dam with the
+
−
purpose of redistributing that sand and mud from the channel bed to eddies. The long-term effect
+
−
of the HFE Protocol depends on the relative “gain” to eddy sandbars that occurs during the short
+
−
controlled floods and the intervening “loss” that occurs during other times. The Environmental
+
−
Assessment for Development and Implementation of a Protocol for High-Flow Experimental
+
−
Releases from Glen Canyon Dam (hereafter referred to as the HFE Protocol EA) asked, "Can
+
−
sandbar building during HFEs exceed sandbar erosion during periods between HFEs, such that
+
−
sandbar size can be increased and maintained over several years?" In other words, does the
+
−
volume of sand aggraded into eddies and onto sandbars during controlled floods exceed the
+
−
volume eroded from sandbars during intervening dam operations?
+
  
−
Thus, one of the most important objectives of this project is to monitor the changes in
+
*[https://www.usbr.gov/uc/rm/amp/amwg/mtgs/10feb03/Attach_19.pdf AIF: FY2009 Final Expenditures and USBR Report]
−
sandbars over many years, including a period that contains several controlled floods, in order to
+
*[https://www.usbr.gov/uc/rm/amp/amwg/mtgs/10feb03/Attach_20.pdf FY2009 Expenditures for USGS]
−
compile the information required to answer the fundamental question of the HFE Protocol EA.
+
−
The monitoring program described here continues the program implemented in the FY13–14
+
−
Biennial Work Plan and is based on annual measurements of sandbars, using conventional
+
−
topographic surveys supplemented with daily measurements of sandbar change using ‘remote
+
−
cameras’ that autonomously and repeatedly take photographs. Because these long-term
+
−
monitoring sites represent only a small proportion of the total number of sandbars in Marble and
+
−
Grand Canyons, this project also includes (1) the analysis of a much larger sample of sandbars,
+
−
using airborne remote-sensing data of the entire CRe collected every 4 years, and (2) periodic
+
−
measurements of nearly all sandbars within individual 50 to 130 km river segments.
+
  
−
Another critical piece of information that will be needed to evaluate the outcome of the HFE
+
|-
−
Protocol and the LTEMP EIS will be the change in total sand storage in long river segments.

−
HFEs build sandbars by redistributing sand from the low-elevation portion of the channel to
+
|-
−
sandbars in eddies and on the banks. The sand available for bar building is the sand that is in
+
|style="color:#000;"|
−
storage within the channel, which is the sum of the sand contributed by the most recent tributary
+
−
inputs, all the sand that has accumulated during the decades since Glen Canyon Dam was
+
−
completed, and any sand that remains from the pre-dam era. The goal of the HFE protocol is to
+
−
accomplish sandbar building by mobilizing only as much sand as is most recently contributed by
+
−
the Paria River. Some of the mobilized sand is deposited in eddies where it maintains and builds
+
−
eddy sandbars. Some of the sand is eventually transported downstream to Lake Mead reservoir.
+
−
The most efficient floods for the purposes of sandbar building are those that maximize eddy
+
−
sandbar aggradation yet minimize the amount of sand transported far downstream, thus
+
−
minimizing losses to sand storage. Dam operations between HFEs also transport sand
+
−
downstream, causing decreases in sand storage. If sand storage is maintained or increased,
+
−
scientists expect the response to future HFEs to be similar to or better than that observed
+
−
following recent HFEs. In contrast, depleted conditions of fine sediment in the active channel are
+
−
potentially irreversible and threaten the long-term ability to rehabilitate eddy sandbars. Although
+
−
the total amount of sand in the active channel is not known and may never be known, changes in
+
−
the topography of the channel measured in this project reveal where fine sediment accumulates,
+
−
where it becomes depleted, and whether or not older fine sediment deposits are being
+
−
progressively eroded by HFEs and other parts of the flow regime.

−
The rate and magnitude of wind transport of sand from active channel sandbars to higher
+
<!--
−
elevation valley margins potentially affects the stability of archaeological sites and the
+
−
characteristics of other cultural and natural resources. The degree to which valley margin areas
+
−
are affected by upslope wind redistribution of sand is called “connectivity”. Connectivity is
+
−
affected by several factors including the sand source as well as physical and vegetative barriers

−
to sand transport. The primary hypothesis of this project is that high degrees of connectivity lead

to potentially greater archaeological site stability.

have shown that the productivity of this foodbase is low. Further, the foodbase in Grand Canyon

is dominated by only two groups of invertebrates: midges and blackflies, both of which are

|style="color:#000;"|
−
small-bodied, relatively low-quality prey. Larger, more nutritious aquatic insects such as
+
−
mayflies, stoneflies, and caddisflies (hereafter, EPT), are virtually absent throughout Glen,

−
Marble, and Grand Canyons. These conditions of low invertebrate productivity and the absence

−
of high quality invertebrate prey have resulted in a fishery throughout Glen, Marble, and Grand

Canyons that is food-limited, negatively affecting the abundance of native fishes such as

humpback chub (Gila cypha), as well as the growth of recreationally-important non-native

rainbow trout (Oncorhynchus mykiss). If the factors and stressors affecting this low foodbase

−
sampling emergent aquatic insect adults on land, and sampling aquatic invertebrate larvae in the

drift. Sampling emergent insects allows for the observation of large-scale patterns in insect

dynamics through time and over large spatial scales, such as throughout the entire Colorado

−
River in Grand Canyon. In contrast, sampling invertebrate drift allows us to understand the finescale

factors affecting invertebrate populations, particularly during a phase (drifting in the water

column) in which these invertebrates are most available to fish. To a lesser extent, we also

describe the continuation of a monitoring effort to estimate algae production in the Colorado

productivity, diversity, and EPT abundance throughout tailwaters in the Intermountain West. We

−
will couple this synthesis with natural history observations and lab studies of invertebrates in the

Colorado River and adjacent ecosystems. The goal of those studies is to better understand how
+
−
the specific insects present in the Colorado River and its tributaries in Glen, Marble, and Grand
+
−
Canyons respond to environmental conditions such as altered temperature regimes and daily
+
−
hydropeaking. We also propose to carry out insect emergence and drift studies in other Colorado
+
−
River Basin tailwaters and in Cataract Canyon to better characterize aquatic foodbase conditions
+
−
in reference ecosystems, and to determine whether the foodbase downstream of Glen Canyon is
+
−
unique, or broadly similar to other river segments in the region. Finally, based on logic described
+
−
below, we identify recruitment limitation of insects as a primary stressor limiting both
+
−
invertebrate production and the colonization of EPT in the Colorado River in Glen, Marble, and
+
−
Grand Canyons. Accordingly, we outline a flow experiment that could be implemented in FY15–
+
−
17 involving weekend summer steady flows that may mitigate this recruitment limitation. If
+
−
successful, this experiment would improve the short- and long-term productivity and diversity of

the aquatic foodbase and, ultimately, the condition of fish populations and the stability of food

webs in the Colorado River.

fish populations, particularly the endangered humpback chub (Gila cypha), be available to

managers. A suite of adaptive experimental management actions are either underway or being

contemplated to better understand the mechanisms controlling the population dynamics of fish in

the Colorado River in Glen and Grand Canyons and to identify policies that are consistent with

humpback chub and rainbow trout (Oncorhynchus mykiss) both in the reach of the Colorado

River from Glen Canyon Dam to the Little Colorado River (LCR) confluence and in the LCR

itself (see Projects 7 and 9). While this work is important and meets critical information needs, it

is also important to have robust monitoring of mainstem fish populations downstream of the

controlling native and nonnative fish population dynamics, determine the effects of dam

some aggregations appear to have increased their distribution (Persons and others, in

evaluate the efficacy of a mark-recapture approach downstream of the LCR confluence. To

eliminate duplicative efforts, we propose that sampling be conducted in areas not sampled by the

−
Rainbow Trout Natal Origins and the Juvenile Chub Monitoring projects (Project Elements 7.2

and 9.2). We will also increase sampling effort downstream of Diamond Creek to monitor for

native and non-native fishes. Continued concerns over upstream movement of non-native

warmwater predatory species such as striped bass (Morone saxatilis), largemouth bass

−
(Micropterus salmoides), channel catfish (Ictalurus punctatus) and walleye (Sander vitreus)
+
−
from Lake Mead highlight the need to continue to monitor the river for non-native fishes.
+
−
Electrofishing is effective at capturing bass species, sunfishes (Centrarchidae), and walleye, so
+
−
this sampling should detect upstream movements of these species. Channel catfish on the other

−
hand, are not effectively captured by electrofishing, so monitoring of catfish distribution by
+
−
standardized angling (Persons and others, 2013) will continue during electrofishing trips.
+
−
Standardized electrofishing sampling is also effective at capturing native sucker species
+
−
including flannelmouth sucker (Catostomus latipinnis), bluehead sucker (Catostomus

−
discobolus), and razorback sucker (Xyrauchen texanus). Recent captures of razorback sucker

monitoring will help document if this once extirpated species continues its apparent recolonization

of Grand Canyon.

+
−
Nonnative brown trout are effective fish predators known to preferentially prey on native
+
−
Colorado River fishes including humpback chub (Yard and others, 2011). Determining the

source or sources of this species in Grand Canyon will help scientists and managers better target

efforts aimed at controlling this threat to native fish populations (see Project Element 8.1).

Project Element 6.5 will conduct research on the use of brown trout pigment patterns to identify

−
natal origins of brown trout; data and images will be collected during the System Wide
+
−
Electrofishing Project and other projects that encounter brown trout.
+
−
One risk to the Grand Canyon humpback chub population is that it includes only one selfsustaining
+
−
spawning population, the LCR aggregation. The USFWS has identified the
+
−
establishment of a second self-sustaining spawning population of humpback chub as an

important step towards recovery of this endangered species (U.S. Fish and Wildlife Service

1995). Project Element 6.6 will develop plans and conduct necessary compliance activities to

to adulthood is relatively rare, with the exception of young-of-the-year outmigration and that
+
−
growth and survival rates are very different in these two environments. This journal article also
+
−
identified the need for studies of trap avoidance among older humpback chub in the LCR, a need
+
−
that can potentially be addressed by increased use of remote technologies for detecting
+
−
humpback chub. We then used a modified version of these models to explain interannual
+
−
variability in mainstem growth and survival in terms of monthly temperature and estimated
+
−
rainbow trout (Oncorhynchus mykiss) abundances in order to support the development of the
+
−
Glen Canyon Dam Long-Term Experimental and Management Plan (LTEMP) Environmental
+
−
Impact Statement and address the key uncertainty surrounding the relative importance of
+
−
rainbow trout and temperature in humpback chub population dynamics (Yackulic and others, in
+
−
prep.). While parameter estimates in these models are based on field data collected in the LCR
+
−
and JCM, this modelling was aided conceptually by lab experiments exploring impacts of trout
+
−
and temperature on chub growth and survival (Ward and others, in prep).
+
−
 
+
−
Simulating future dynamics under alternative management strategies as part of the LTEMP
+
−
process highlighted the importance of uncertainty associated with several key population
+
−
processes, especially the production and outmigration of young-of-the-year humpback chub from
+
−
the LCR. Available information suggests that the number of Age-0 chub present in July in the
+
−
LCR has varied from roughly 5,000 to 50,000 in recent years and that the overall outmigration
+
−
rate can vary from 25% to 75%. To address this uncertainty, already identified in the Grand
+
−
Canyon Monitoring and Research Center’s workplan for Fiscal Years (FY) 2013–14, we initiated
+
−
juvenile humpback chub marking with visible implant elastomer (VIE) tags in the LCR during
+
−
early July, a period when humpback chub are just becoming large enough to have a reasonable
+
−
chance of surviving in the mainstem. Although LTEMP obligations have delayed a formal
+
−
analysis of these data, preliminary work suggests that this effort will allow us to estimate
+
−
juvenile humpback chub abundance and outmigration with acceptable precision. We also
+
−
analyzed data collected by the U.S. Fish and Wildlife Service (USFWS) from 2001–2013 to
+
−
characterize spatio-temporal variation in survival, growth and movement of sub-adult humpback
+
−
chub in the LCR (Dzul and others, in review). This work suggests both that winter growth is
+
−
strongly and negatively correlated with the extent of winter/spring flooding and that habitat
+
−
quality for sub-adult humpback chub is better in upper reaches of the LCR. This follows work by
+
−
Vanhaverbeke and others (2013) indicating that when winter/spring flooding was minimal,
+
−
juvenile production was poor. Other activities during FY13–14 included pilot work to determine
+
−
the best ways to characterize spatio-temporal variation in the food base in FY13, with plans to
+
−
rigorously sample the LCR food base in calendar year 2014.
+
−
 
+
−
In FY15–17, we will: (a) continue to monitor humpback chub in the LCR and Colorado
+
−
River reference site (river mile (RM) 63.0-64.5) and to mark young-of-year humpback chub
+
−
throughout the lower 13.6 km of the LCR in July, (b) develop field and analytical techniques to
+
−
better use remote technologies for detecting passive integrated transponder (PIT) tags to address
+
−
questions of trap avoidance and to potentially minimize future handling of chub, (c) develop new
+
−
non-lethal tools for measuring the health and condition of humpback chub in the field, (d)
+
−
undertake targeted, cost-effective research to understand mechanisms underlying observed
+
−
population processes, including the roles of high CO2 at base flow, gravel limitation, parasites,
+
−
and the aquatic food base, and (e) continue to develop models that integrate findings from the
+
−
above projects. The proximate goals of these activities is to better understand the relative roles of
+
−
LCR hydrology, water quality, intraspecific and interspecific interactions, and mainstem
+
−
conditions in humpback chub juvenile life history and adult recruitment, as well as to better
+
−
estimate the current adult abundance. The ultimate goal of these activities is to continue to
+
−
develop tools that allow us to better predict the impacts of dam operations and other management
+
−
activities on humpback chub populations as well as appropriately account for uncertainty in these
+
−
predictions. Specific questions of interest include:
+
−
 
+
−
#To what extent does young-of-the-year humpback chub production and outmigration from the LCR vary between years and how is this variation driven by LCR hydrology and intraspecific interactions (i.e., cannibalism and competition)?
+
−
#What are the drivers of interannual and spatial variation in survival and growth of juvenile and sub-adult humpback chub? In particular, what are the roles of LCR and mainstem conditions in the overall trajectory of the population?
+
−
#Are there factors, such as heterogeneity in skip-spawning rates, heterogeneity in adult humpback chub capture probabilities in the JCM, or trap avoidance in the LCR that bias estimates of the adult population size and population processes?
+
−
 
+
−
Juvenile humpback chub are the most sensitive life stage to mainstem conditions and an
+
−
understanding of their life history is the key to predicting the influence of dam operations on this
+
−
species. Prior to the Near Shore Ecology (NSE) project (2009–2011) and the more recent JCM
+
−
project (2012–current), our understanding of humpback chub early life history was limited to
+
−
back-calculations of cohort strength (number of fish surviving to adulthood from a given hatch
+
−
year) derived from abundance estimates of humpback chub greater than 200 mm and believed to
+
−
be four years old (Coggins and others, 2006; Coggins and Walters, 2009). However, given the
+
−
disparity in growth rates between humpback chub living in the LCR and Colorado River
+
−
(Yackulic and others, 2014) this approach was almost certainly misleading as humpback chub
+
−
could be anywhere from 4–10 years old when they reach 200 mm depending on where they had
+
−
spent most of their time (LCR or mainstem Colorado River) and what environmental conditions
+
−
had been like in those locations.
+
−
 
+
−
Since 2009, we have developed the field techniques (including a fixed reference site in the
+
−
Colorado River) and analytical methods that allow us to understand humpback chub early life
+
−
history in the detail required to begin to tease apart the effects of variation in population
+
−
processes caused by mainstem temperature, trout abundance, and conditions in the LCR. For
+
−
example, in support of the LTEMP process we were able to fit relationships between monthly
+
−
temperature and estimated rainbow trout abundance and juvenile humpback chub survival and
+
−
growth using only data from 2009–2013 that accurately predicted trends in adult humpback chub
+
−
numbers from 1989–2009 (Figure 1). While there is still room for improvement in these models,
+
−
this represents a dramatic step in our ability to predict the consequences of management options.
+
−
While conditions in the LCR are not directly affected by dam operations, they nonetheless play a
+
−
vital role in determining the degree to which temperature and rainbow trout numbers in the
+
−
Colorado River must be managed (Figure 2). For example, if juvenile humpback chub
+
−
production and export are high, this may suggest less need for rainbow trout management and/or
+
−
lower flows to increase water temperatures in the mainstem. Alternatively, a better understanding
+
−
of the factors leading to increased humpback chub production could provide decision makers
+
−
opportunities to strategically implement management actions in years when they would have the
+
−
largest effect. For example, the 2000 Low Steady Summer Flow experiment may have been
+
−
ineffective simply because it followed two years of potentially minimal production of juvenile
+
−
chub. Improved information about the drivers of humpback chub population dynamics could
+
−
have helped managers and scientists plan this experiment such that it occurred when conditions
+
−
were more likely to result in a detectable response. Likewise, management actions such as
+
−
mechanical removal of nonnative fishes will be much more effective if they occur in years of
+
−
high humpback chub production. If variation in production is primarily driven by exogenous
+
−
factors (e.g., extent of flooding) as opposed to endogeneous factors (e.g., competition between
+
−
cohorts) this also has implications for long-term population dynamics.
+
−
 
+
−
With respect to adult humpback chub, key uncertainties revolve around our understanding of
+
−
capture probability and movement. In particular, heterogeneity in capture probability in the LCR
+
−
caused by some adult humpback chub (especially potential residents) avoiding hoop nets could
+
−
lead to underestimates of abundance. At the same time, the potential for temporary emigration in
+
−
the JCM reach is a cause for concern and could lead to overestimates of abundance. Lastly, a
+
−
better understanding of skip-spawning in adult humpback chub is essential because many adults
+
−
are only vulnerable to capture during spring sampling in the LCR and thus inferences about their
+
−
survival and abundance depends on assumptions about the skip-spawning process. Answering
+
−
the above uncertainties is dependent both on new data streams from remote tag readers and
+
−
intellectual investment into developing the appropriate models to incorporate this information
+
−
and test hypotheses.

==Project 8. Experimental Actions to Increase Abundance and Distribution of Native Fishes in Grand Canyon==
+
−
 
+
−
This project encompasses two ongoing management actions and two new projects, all
+
−
designed to increase survival of juvenile native fishes in Grand Canyon. In addition, we propose
+
−
to convene a protocol evaluation panel comprised of external experts to conduct a review of the
+
−
fisheries research, monitoring, and management actions conducted in support of the Glen
+
−
Canyon Dam Adaptive Management Program (GCDAMP). In FY15–17 we will continue
+
−
ongoing mechanical removal of rainbow trout (Oncorhynchus mykiss) and brown trout (Salmo
+
−
trutta) using electrofishing near the confluence of Bright Angel creek, in support of Grand
+
−
Canyon National Park’s goals to reduce nonnative fish abundance in and around Bright Angel
+
−
Creek for the benefit of juvenile native fish. We will also continue to translocate juvenile
+
−
humpback chub (Gila cypha) annually from the Little Colorado River (LCR) into areas within
+
−
the LCR and continue to support translocation efforts into Havasu Creek and Shinumo Creek, to
+
−
increase survival and distribution of humpback chub. In FY16 or FY17 we will participate in a
+
−
review by external experts of these activities and other fisheries projects (see Projects 6, 7, and
+
−
9). The review of Project 8 activities will emphasize evaluation of the effectiveness of these
+
−
experimental actions in meeting GCDAMP or National Park Service (NPS) goals and objectives
+
−
as appropriate, and the panelists will be asked to make recommendations as to how projects can
+
−
be adapted to meet project goals and objectives and whether the continuation of these efforts are
+
−
warranted in future years. NPS will also consider the review panel’s recommendations, but any
+
−
changes in implementation are under the discretion of the NPS consistent with the
+
−
Comprehensive Fish Management Plan for Grand Canyon National Park (NPS, 2013). This
+
−
project also includes two new project elements that will inform future potential management
+
−
actions: 1). An assessment of invasive aquatic species within the LCR drainage, to evaluate
+
−
potential risks to humpback chub populations and 2.) Genetic monitoring of humpback chub to
+
−
confirm that ongoing management activities do not have detrimental effects on the genetics of
+
−
the Grand Canyon population of this endangered species.
+
−
 
+
−
==Project 9. Understanding the Factors Determining Recruitment, Population Size, Growth, and Movement of Rainbow Trout in Glen and Marble Canyons ==
+
−
 
+
−
Over the past few decades, electrofishing and creel monitoring data collected by Arizona
+
−
Game and Fish Department (AGFD) in Glen Canyon and Lees Ferry has shown that the rainbow
+
−
trout (Oncorhynchus mykiss) fishery is characterized by three undesirable properties, including:
+
−
(1) instability in population size that has led to decadal cycles of high and low fish abundance;
+
−
(2) increased potential for negative interactions between rainbow trout and native fishes,
+
−
especially the endangered humpback chub (Gila cypha), primarily due to rainbow trout
+
−
population expansion downstream (Yard and others, 2011); and (3) an absence of the large
+
−
rainbow trout that are highly valued by the angling community (Schmidt and others, 1998).
+
−
Accordingly, much of the recent biological research conducted in Glen and Marble Canyons has
+
−
focused on understanding factors that influence the size and health of the rainbow trout fishery
+
−
(Korman and Campana, 2009; Anderson and others, 2012; Cross and others, 2013), as well as
+
−
determining how Glen Canyon Dam operations and other factors may influence interactions
+
−
between non-native trout and native species downriver (Yard and others, 2011; Korman and
+
−
others, 2012; Melis and others, 2012).
+
−
 
+
−
These undesirable properties have also been a key concern to decision makers involved with
+
−
the development of the Glen Canyon Dam Long-Term Experimental and Management Plan
+
−
(LTEMP) Environmental Impact Statement. Fisheries modelling conducted to support the
+
−
LTEMP process has identified a number of factors that lead to uncertainty in our ability to
+
−
predict rainbow trout responses to flow management. Uncertainties identified prior to modelling
+
−
as “critical” included the degree to which the seasonal timing of high flow experiments (HFEs)
+
−
versus other factors contributes to variation in the strength of the trout recruitment response, and
+
−
the degree to which experimental trout management flows (TMFs), if implemented, could limit
+
−
rainbow trout recruitment in Glen Canyon (as well as other chub related uncertainties – see
+
−
Project 7). The modelling also included other uncertainties, including the uncertainty in
+
−
recruitment-flow relationships, rates of rainbow trout outmigration from Glen Canyon, and the
+
−
degree to which larger rainbow trout populations in Lees Ferry limit trout growth. Modelling
+
−
revealed that these other uncertainties had a large impact on variation in predictions, a similar
+
−
effect to the “critical” uncertainties, and generally larger uncertainty in hydrologic traces over the
+
−
next 20 years. Resolving uncertainty in the “critical” uncertainties as well as the recruitmentflow
+
−
relationships will require the continuation of sampling focused on juvenile rainbow trout
+
−
recruitment (i.e., RTELLS) alongside a well-designed plan for testing different flow management
+
−
strategies (assuming that refining these uncertainties is necessary for management). Uncertainties
+
−
in our ability to predict outmigration rates and growth, on the other hand, requires a combination
+
−
of mark-recapture techniques which provide more precise estimates of movement and survival
+
−
parameters, and process levels studies to better understand how movement and growth might
+
−
respond to future conditions.
+
−
 
+
−
The Natal Origins Project (see Project Element H.2 in the GCMRC FY13–14 workplan) was
+
−
designed to address the need for mark-recapture studies to better understand rainbow trout
+
−
population dynamics, especially movement. Previous modelling work using just catch data found
+
−
it difficult to parse out whether local reproduction in Marble Canyon contributed meaningfully to
+
−
populations or whether population dynamics were driven primarily by outmigration from the
+
−
Lees Ferry reach (Korman and others, 2012). Preliminary results from the Natal Origins study
+
−
suggest that movement is lower than expected, however, it is unclear whether movement rates
+
−
may vary over time either as fish age or in response to changing environmental conditions.
+
−
Furthermore, it is unclear how well these drift-feeding fish can maintain locally self-sufficient
+
−
populations in Marble Canyon where environmental factors (i.e., reduced underwater light due to
+
−
intermittent periods of high turbidity) may influence their ability to effectively forage (Kennedy,
+
−
unpublished data). Another unknown is why local reproduction does not occur in Marble Canyon
+
−
more than it does in Glen Canyon (Korman and others, 2012; also see Project 10).
+
−
Physiologically, fish that exhibit reduced foraging capacity because of low light conditions
+
−
and/or prey size and availability will often not be able to successfully spawn since gamete
+
−
development is energetically costly (Hutchings, 1994; Hutchings and others, 1999). For the
+
−
FY15–17 workplan, we developed a suite of research and monitoring projects that will elucidate
+
−
some of the mechanisms behind changes in trout abundance, survival, movement, reproduction,
+
−
and growth in Glen and Marble Canyons. These research efforts will provide information that
+
−
can be used to better understand the potential for negative interactions between non-native trout
+
−
and native species like humpback chub, and perhaps identify experimental treatment options for
+
−
mitigating high rainbow trout abundance downstream of Lees Ferry.
+
−
 
+
−
Since the early 1990’s the Arizona Game and Fish Department (AGFD) has monitored the
+
−
Lees Ferry rainbow trout fishery via electrofishing in multiple seasons, providing data that has
+
−
fostered the development of research projects to investigate causal mechanisms behind changes
+
−
in population and trout size over time. These data have been used to develop catch per unit effort
+
−
(CPUE) indices as a surrogate for population size, but other research and monitoring programs
+
−
have commenced that estimate population size via more robust mark-recapture methods. To
+
−
reduce redundancy between programs and optimize the utility of data generated (e.g., mark recapture
+
−
population estimates in lieu of CPUE), a transition is needed from current research and
+
−
monitoring efforts to a longer-term monitoring program that maintains a robust multi-pass mark recapture
+
−
effort necessary to generate reliable estimates of vital rates for rainbow trout in Glen
+
−
and Marble Canyons. We propose to develop and implement a plan for this transition during
+
−
FY2015-17. Monitoring of juvenile trout will also continue under the Rainbow Trout Early Life
+
−
Stage Survey (RTELSS) project (Project Element 6.7), while creel data from the Lees Ferry
+
−
fishery will continue to be collected by AGFD (Project Element 6.8). Collectively, these
+
−
monitoring data are essential to the management of the Lees Ferry trout fishery because they
+
−
provide an indication of the influence of Glen Canyon Dam operations and other naturally
+
−
occurring disturbances in the Colorado River ecosystem (CRe) on the health of the rainbow trout
+
−
fishery.
+
−
 
+
−
In addition to monitoring adult and juvenile rainbow trout populations, a suite of new
+
−
research activities will improve our understanding of the mechanisms that drive rainbow trout
+
−
population dynamics as they relate to dam operations and flow management actions.
+
−
Specifically, these research projects will target questions related to characteristics of the physical
+
−
habitat (e.g., channel-bed texture, water temperature, turbidity, water depth, and flow) and food
+
−
base that may limit trout growth, size, and reproduction including: (a) a quantification of the
+
−
energy (lipid) reserves of drift-feeding trout in Glen and Marble Canyons to examine potential
+
−
drivers of trout growth, movement, survival, and reproduction under varying light intensities prea nd
+
−
post-monsoon; (b) a morphometric analysis of feeding structures in drift feeding fish to
+
−
assess whether feeding efficiency is constrained by the size of invertebrate prey in the CRe; (c) a
+
−
meta-analysis of data on the effects of light intensity, prey size, predator size, and turbidity on
+
−
visual reactive distances of drift feeding fish, which will be used to develop an encounter rate
+
−
model that predicts how light intensity and prey size affects trout foraging success and growth in
+
−
Glen and Marble Canyons; (d) a laboratory study to assess the feasibility of using dam
+
−
operations following fine sediment inputs (sub-sand sized) into Marble Canyon so as to assess
+
−
whether or not managing turbidity is feasible as a trout management tool during minimum volume
+
−
dam release years; (e) development of bioenergetics models to quantify the effects of
+
−
turbidity and food availability on trout growth in Marble Canyon; (f) an assessment of the
+
−
mechanisms that limit trout growth in other tailwaters using data collected during the tailwater
+
−
synthesis project; (g) development of population dynamic models that assess growth,
+
−
reproduction and movement of rainbow trout between Glen and Marble Canyons; and (h) an
+
−
evaluation of the effects of fall High Flow Experiments (HFE) on the growth, survival,
+
−
movement, and condition of young-of-the-year rainbow trout via comparison of data from HFE
+
−
and non-HFE sampling years. Collectively, results from these monitoring and research projects
+
−
will be used to identify key drivers behind changes in rainbow trout population size, movement,
+
−
survival, reproduction, size, and condition that will be used to better manage the trout fishery
+
−
while protecting endangered fish populations in the CRe.

==Project 10. Where does the Glen Canyon Dam rainbow trout tailwater fishery end? - Integrating Fish and Channel Mapping Data below Glen Canyon Dam ==
+
−
 
+
−
Glen Canyon Dam’s rainbow trout tailwater fishery (hereafter, GCD tailwater) begins in the
+
−
project’s tailrace, but where does it end? The serial discontinuity concept for impounded rivers
+
−
was first described by Ward and Stanford (1983), whereby recovery of river ecosystems
+
−
impaired by dams is predicted to increase with distance below dams; often influenced by
+
−
locations of downstream tributaries that to some degree add back resources lost to upstream
+
−
reservoirs. The Colorado River ecosystem (CRe) is composed of several river segments
+
−
extending from the forebay of GCD to the western boundary of GCNP, and has been studied
+
−
extensively for the past five decades (Gloss and others, 2005; Schmidt and Grams, 2011a).
+
−
However, it remains unclear how long-term trends in the river’s channel morphology in response
+
−
to dam operations, will combine with climate-change induced trends in downstream quality-of water
+
−
(QW) to influence the exotic rainbow trout tailwater fishery and native fish in the CRe.
+
−
Stream forecasting under current climate change for the southwestern US and Colorado River
+
−
suggests dryer conditions are already occurring under global warming (see chaps. 8 & 20 of the
+
−
2014 National Climate Assessment: http://nca2014.globalchange.gov/report).
+
−
 
+
−
Reduced water storage in Lake Powell since 2001, has already resulted in warmer GCD
+
−
releases; a trend that has significantly influenced the discontinuity distance and recovery relative
+
−
to the river’s altered thermal regime in Grand Canyon over the last 14 years. Whether exotic or
+
−
native fish species in GCNP will benefit more from these somewhat warmer, but still unnaturally
+
−
cold releases under both drier and warmer conditions below GCD remains highly uncertain.
+
−
Located 15 miles below GCD, the confluence with the Paria River is typically referred to as the
+
−
downstream terminus of the “Lees Ferry” recreational trout fishery, and is also the approximate
+
−
boundary between Glen Canyon National Recreation Area and Grand Canyon National Park
+
−
(GCNRA and GCNP, respectively). However, rainbow trout are also found below the Paria and
+
−
Little Colorado Rivers, more than 75 miles downstream of the dam (Makinster and others, 2010).
+
−
Recent modeling studies suggest that sand-sized sediment can be a significant limiting factor in
+
−
the spawning success of trout in gravel-bed settings, and may be more important than finer
+
−
sediments in limiting flow and reducing levels of dissolved oxygen needed by incubating trout
+
−
eggs within redds (Pattison and others, 2012; Sear and others, 2012). The highly sporadic and
+
−
intermittent nature of flooding and sediment production from the Paria River results in periods
+
−
when the Colorado River’s bed and water quality may or may not be greatly affected by fine sediment
+
−
deliveries from this important tributary. Paria River flow volumes are relatively small
+
−
and typically have little influence on the now-altered temperature regime of the Colorado River
+
−
below Glen Canyon. Therefore, the effective “discontinuity distance” below GCD may be highly
+
−
variable through time relative to the Paria River’s location below the dam.
+
−
 
+
−
Ellis and Jones (2013) conclude that at least two recovery gradients exist in regulated rivers,
+
−
with the thermal recovery gradient typically being the longest. To improve understanding about
+
−
discontinuity distance(s) associated with the GCD tailwater, this interdisciplinary research
+
−
project proposes to integrate new and existing channel mapping methods with ongoing fisheries
+
−
monitoring and analyses using a variety of information about the geometry of channel margins,
+
−
bed-sediment characteristics (softer (sand and finer) and harder (gravel or bedrock) substrates),
+
−
and quality of water (QW) data (including, flow, water temperature and turbidity or total
+
−
suspended sediment). This project’s aim is to evaluate the potential effects of physical processes
+
−
(water temperature and sediment input frequency) on native and nonnative fish dynamics. The
+
−
basic questions being asked are: 1) How do seasonal fine-sediment inputs, high flow events and
+
−
dam release temperatures affect downstream spawning for rainbow trout, and rearing habitat for
+
−
trout and humpback chub? and, 2) Do fall-timed pulse flows extend the rainbow trout fishery
+
−
downstream toward or beyond the Little Colorado River? Sources of information needed to
+
−
address these questions are shown in figure 1.
+
−
 
+
−
The CRe’s thermal recovery gradient has moved upstream since 2002, in response to reduced
+
−
Lake Powell storage, while highly variable point sources of fine sediment influencing turbidity remained fixed.
+
−
This information has management implications, particularly below GCNRA where rainbow
+
−
trout are of concern relative to native fish conservation in GCNP. Understanding the
+
−
relationships between trout life history, and abiotic and biotic processes affected by specific dam
+
−
operations and climate change will provide greater insight about strategies for co-managing
+
−
native and nonnative fisheries between Lakes Powell and Mead. Project findings may also be
+
−
transferable to inform management of other Colorado River basin tailwaters where similar
+
−
challenges in co-management of native and nonnative sport fisheries exist (see Trammel, 2010;
+
−
Clarkson and Marsh, 2010).
+
−
 
+
−
As shown in figure 1, this project intends to build on the numerous recent achievements of
+
−
several FY13–14 projects, including near real time monitoring of flow, QW and suspended sediment
+
−
transport (Topping and others, Project 2), annual channel mapping of sandbars (Grams
+
−
and others, Project 3), quarterly monitoring of natal origins (NO) of rainbow trout and humpback
+
−
chub juvenile survival (Korman and Yard, Project 9), and ongoing monitoring of the CRe’s food
+
−
base (Kennedy and others, Project 5). Proposed interdisciplinary analyses of fish and channel map
+
−
data also critically depend upon the capabilities of the GCMRC’s GIS Services and Support
+
−
project, as well as GCMRC’s abundant existing remote sensing data (Gushue and others, Project
+
−
14).
+
−
 
+
−
We propose to use both new and existing channel mapping data (Table 1) to advance an
+
−
integrated physical and biological outcome that is only possible owing to ongoing QW and
+
−
channel monitoring, as well as NO and food base field monitoring during 2015-16. Outcomes
+
−
from other monitoring projects focused on riparian vegetation and cultural resources (Projects 11
+
−
and 12) will also be considered in terms of channel-shoreline changes in NO study reaches as
+
−
appropriate and available during project synthesis in 2017.

Riparian vegetation affects physical processes and biological interactions along the channel
+
−
downstream of Glen Canyon Dam. The presence and expansion of riparian vegetation promotes
+
−
bank stability, diminishes the magnitude of scour and fill during floods, and has a role in wildlife
+
−
habitat and recreational values. This project utilizes annual field measurements and digital
+
−
imagery for integrated monitoring of changes in vegetation assessed within a hydro-geomorphic
+
−
context. Research elements of this project utilize the monitoring data to explore the utility of
+
−
plant response-guilds to probabilistically evaluate and assess wildlife habitat, and integrate the
+
−
response guilds with a 22-year topographic survey record for retrospective analyses of
+
−
topographic change of 20 sandbars. This project builds upon accomplishments associated with
+
−
the FY13/14 Work Plan, provides information that support stakeholder needs as identified by
+
−
guiding documents developed by the Adaptive Management Program, and furthers our
+
−
understanding of the role of riparian vegetation in ecosystem processes in a regulated river
+
−
ecosystem.
+
−
 
+
−
The objectives and elements of this monitoring and research project are:
+
−
# Measurement and analysis of plant cover and species presence to assess change as related to the geomorphic setting, elevation above the channel, and flow regime (Project Element 11.1)
+
−
# Mapping changes in woody vegetation at the landscape scale through image processing, classification, and analysis (Project Element 11.2)
+
−
# Utilizing vegetation response-guilds for integrated research of sandbars and riparian vegetation (Project Element 11.3)
+
−
# Use multiple sampling approaches and historic data sets to quantify the strength of aquatic-terrestrial linkages and the relative importance of vegetation change and aquatic production in driving the population dynamics of a subset of the terrestrial fauna (Project Element 11.4).
+
−
# A review and assessment of nonnative plant control and native plant restoration efforts along regulated segments of the Colorado and Rio Grande Rivers (Project Element 11.5).
+
−
 
+
−
Each of these objectives and the associated project elements inform stakeholders about the
+
−
status of vegetation and support analysis of vegetation’s role in the ecological, physical,
+
−
sociocultural responses to dam operations.

==Project 12. Changes in the Distribution and Abundance of Culturally-Important Plants in the Colorado River Ecosystem: A Pilot Study to Explore Relationships between Vegetation Change and Traditional Cultural Values==
+
−
 
+
−
The river corridor landscape in lower Glen Canyon and Grand Canyon National Park has
+
−
undergone significant change during the past several decades. Some of those changes, especially
+
−
in terms of vegetation, are the result of river regulation by Glen Canyon Dam. The Glen Canyon
+
−
Dam Adaptive Management Program supports a $10 million program of research and monitoring
+
−
to study and document linkages between river regulation and riparian responses; however, few
+
−
GCDAMP studies have attempted to understand how the changes being documented by GCMRC
+
−
scientists affect cultural perceptions and values of the diverse stakeholders in the GCDAMP.
+
−
This project proposes to begin to fill that gap by undertaking a pilot study to evaluate how
+
−
changes in the riparian assemblage of the river corridor, and specifically in the distribution and
+
−
abundance of culturally-important plant species, has affected attributes of the landscape that are
+
−
culturally-important to Native American tribes.
+
−
 
+
−
This project will involve holding two workshops with tribal stakeholders, riparian ecologists
+
−
and social scientist to explore and discuss linkages between changes in plant distributions and
+
−
abundance and affects to the cultural values associated with plants. We will use these workshops
+
−
to further refine research questions and directions related to changes in the riparian system that
+
−
tribal participants would like to explore through future research and monitoring. As part of this
+
−
project, we will compile and synthesize available data focused initially on a subset of culturally424
+
−
important plant species and conduct some exploratory analyses; however, the larger aim of this
+
−
project is to initiate a dialog on how to evaluate changes in the river corridor landscape that are
+
−
due wholly or in part to dam operations in terms of the affects that these changes may have on
+
−
cultural values and human perceptions of the landscape, especially those values that are
+
−
important to tribal participants in the GCDAMP.
+
−
 
+
−
This project is intended to serve the interests of the tribes involved in the GCDAMP, as well
+
−
as the interests of all GCDAMP stakeholders, in several important respects. At a general level,
+
−
this project proposes to utilize a combination of western scientific data about vegetation in
+
−
combination with traditional ecological knowledge (TEK) to interpret landscape changes from
+
−
tribal perspectives and assess how observed changes to culturally-important plant species affect
+
−
cultural values associated with the riparian corridor. This information will help to inform DOI
+
−
managers and GCDAMP stakeholders about how changes in culturally-valued vegetation species
+
−
of the river corridor’s riparian landscape affect cultural resource values of tribal participants in
+
−
the GCDAMP. More specifically, this project will: 1) integrate Native American values and
+
−
traditional ecological knowledge in a collaborative GCMRC-sponsored science effort that
+
−
assesses potential dam effects to culturally-valued plant components of the Colorado River
+
−
riparian landscape; 2) utilize traditional ecological knowledge to identify plant species of cultural
+
−
importance to multiple tribes, with a focus on plants that are dependent on and potentially
+
−
affected by changes in river hydrology; 3) compile and synthesize existing scientific and
+
−
ethnobotanical information about a subset of culturally-valued plant resources; and 4) utilize a
+
−
combination of traditional ecological knowledge and western scientific information to further
+
−
enhance understanding of how dam operations and other potential agents of change affect
+
−
cultural resource values in the CRe. If, after completing this initial study, tribes decide to
+
−
incorporate the results of this pilot study into their monitoring programs, this could provide
+
−
another mechanism for further enhancing knowledge transfer between tribal elders, youth, and
+
−
non-tribal scientists in the context of tribal monitoring programs. In addition, this project
+
−
supports the interests of multiple GCDAMP stakeholders who would like to see a variety of
+
−
approaches, including more holistic and qualitative methods, used to assess the effects of Glen
+
−
Canyon Dam operations on the riparian landscape and the diverse cultural values of the Colorado
+
−
River corridor. Furthermore, it is aligned with the new Department of Interior Secretarial
+
−
directive to use a landscape approach for assessing and mitigating effects of energy-related
+
−
projects on federal lands (DOI 2013, Secretarial Order No.330).
+
−
 
+
−
==Project 13. Socioeconomic Monitoring and Research==
+
−
 
+
−
During the past three decades, socioeconomic monitoring and research in the Glen Canyon
+
−
Environmental Studies and Glen Canyon Dam Adaptive Management Program (GCDAMP) have
+
−
been limited (Hamilton and others, 2010). Previous research has indicated that the economic
+
−
value of recreation and other downstream resources are impacted by Glen Canyon Dam (GCD)
+
−
operations; however, because these studies were conducted 20 to 30 years ago, the findings are
+
−
out-of-date, as dam operations and resource conditions have changed since that time (Bishop and
+
−
others, 1987; Welsh and others, 1995; U.S. Department of Interior, 1996; USGS, 2005).
+
−
This project is designed to identify recreation and tribal preferences for, and values of,
+
−
downstream resources and evaluate how preference and value are influenced by GCD operations.
+
−
In addition, the research will integrate economic information with data from long-term and
+
−
ongoing physical and biological monitoring and research studies led by the Grand Canyon
+
−
Monitoring and Research Center (GCMRC) to develop a decision support system that will
+
−
improve the ability of the GCDAMP to evaluate and prioritize management actions, monitoring
+
−
and research (Hamilton and others, 2010).
+
−
 
+
−
This project involves three related socioeconomic monitoring and research studies. These
+
−
studies include: (a) evaluation of the impact of GCD operations on regional economic
+
−
expenditures and economic values associated with angling in the Glen Canyon National
+
−
Recreation Area (GCNRA) downstream from GCD, and whitewater floating in Grand Canyon
+
−
National Park (GCNP) that begins at Lees Ferry (Project Element 13.1); (b) assessment of the
+
−
impact of GCD operations on tribal preference for and value of downstream resources (Project
+
−
Element 13.2); and (c) development of decision methods, using economic metrics, to evaluate
+
−
management actions and prioritize monitoring and research on resources downstream of GCD
+
−
(Project Element 13.3).
+
−
 
+
−
This project will be coordinated with related economic research efforts implemented by the
+
−
National Park Service (NPS) and U.S. Bureau of Reclamation (Reclamation) in conjunction with
+
−
the Glen Canyon Dam Long-Term Experimental and Management Plan Environmental Impact
+
−
Statement (LTEMP EIS). The NPS is conducting research to provide current economic values of
+
−
ecosystem resources downstream of GCD. In addition, Argonne National Laboratory, contracted
+
−
through Reclamation, has made significant advancements in the power system analysis modeling
+
−
for the LTEMP EIS that provide information on the economic value of hydropower production at
+
−
GCD under different management alternatives. These coordinated efforts to determine individual
+
−
preferences for and economic values of downstream resources, and the development of decision
+
−
methods to improve decision making abilities of GCDAMP are necessary to evaluate and
+
−
prioritize management, monitoring, and research decisions.
+
−
 
+
−
==Project 14. Geographic Information Systems (GIS) Services and Support ==
+
−
 
+
−
Geographic Information Systems (GIS) continues to play a critical role in nearly all of
+
−
GCMRC’s science efforts and is prevalent in many of the projects proposed in the FY2015-17
+
−
Triennial Work Plan. It is used across disciplines and is itself a powerful tool for integrating
+
−
geospatial data collected by many different projects. The GIS Services and Support project is the
+
−
epicenter of GCMRC’s geospatial knowledge and support for a broad range of activities. It
+
−
supports acquisition of remote sensing overflight data and river-based data collection efforts,
+
−
provides geospatial expertise across all resources of interest, maintains and preserves all
+
−
geospatial data holdings, and produces a wide range of cartographic, geographic and analytical
+
−
output in support of GCMRC’s science projects. Linkages to other projects in this work plan are
+
−
addressed in the Geospatial Data Analysis element of this project (14.1.1.) and more specifically
+
−
outlined in Table 1 at the end of this project description. This project provides a high-level of
+
−
support to other GCMRC projects in the form geospatial data processing and analysis, geospatial
+
−
data management, and the development of web-based services and applications that provide
+
−
access to GCMRC’s geospatial data holdings.
+
−
 
+
−
As we move into a new planning cycle, an opportunity exists to promote a vision of how a
+
−
GIS project will successfully function within GCMRC and meet the current and future needs of
+
−
scientists, managers and the public alike. Most work performed within this project falls within
+
−
one of three main tenets: Geospatial Data Analysis, Geospatial Data Management, and Access to
+
−
Geospatial Data Holdings. These concepts are not new, and have been a part of GCMRC work
+
−
in various forms over the last 15 years or more. This project description affords us a chance to
+
−
more clearly define each of these elements and how they relate to individual projects as well as
+
−
GCMRC’s overall mission.
+
−
 
+
−
==Project 15. Administration==
+
−
 
+
−
The USGS Administration budget covers salaries for the communications coordinator, the
+
−
librarian, and the budget analyst for GCMRC, in addition to monetary awards for all GCMRC
+
−
personnel. The vehicle section covers GSA vehicle costs including monthly lease fee, mileage
+
−
costs, and any costs for accidents and damage. DOI vehicles are also included in this section of
+
−
the budget to pay for vehicle gas, maintenance, and replacements costs. Leadership personnel
+
−
covers salary for the GCMRC Chief and Deputy Chief, half the salary for two program
+
−
managers, and some of the travel and training costs for these personnel. AMWG/TWG travel
+
−
covers the cost of GCMRC personnel to travel to the AMWG and TWG meetings. SBSC
+
−
Information Technology (IT) overhead covers GCMRCs IT equipment costs. Logistics base
+
−
costs covers salaries and travel/training. These base costs also include a $35,000 contribution to
+
−
the equipment and vehicles working capital fund.

In 2003, the GCDAMP established a fund to pay for experimental research projects so that they can be conducted without financially impacting other aspects of the science program. The current balance of the experimental fund at the end of the FY2007 is anticipated to be approximately $900,000. An additional $500,000 will be set aside by the GCMRC annually in an account at Reclamation to fund the BHBF tests and other research related to experimental efforts. Deposits to the experimental account will cease when the balance reaches $2.5 million.[http://gcdamp.com/index.php?title=Monitoring_and_Research_Plan Monitoring and Research Plan, page 8]
 +
 
 +
If the funds allocated to the Experimental Management Fund are not needed in
 +
a given year, at the end of the year, they will be transferred to the Native Fish
 +
Conservation Contingency Fund (Reclamation project C.6); some year-end
 +
experimental management funds may also be allocated to the Contingency
 +
Fund for NHPA Section 106 Compliance (Reclamation project D.10). [https://www.usbr.gov/uc/progact/amp/amwg/2017-09-20-amwg-meeting/Attach_04e.pdf]

GCDAMP Budget and Work Plan


The goal of the Triennial Budget and Workplan (TWP) is to reduce the effort expended on the budget process while improving the effectiveness of the Grand Canyon Monitoring and Research Center (GCMRC), Technical Work Group (TWG), and AMWG. The GCDAMP will develop a TWP the first year of the process. Then, in the second year the GCDAMP would implement the year-two budget and make relatively minor corrections primarily related to changes in CPI and needs at GCMRC and the Bureau of Reclamation. In the third year the GCDAMP would consider minor changes to the year three budget to allow for changes in projects or potential important new starts not envisioned during the development of the triennial budget.

The major components of the TWP would include:

  • Three-year budget spreadsheets, work plans, and hydrographs,
  • Modifications of the year-three budget based on specific criteria,
  • Fiscal reporting, including expenditures for the previous fiscal year (mid-year and end end-of year reports),
  • Project progress reports, including an annual reporting meeting in January, and
  • Utilization of the Budget Ad Hoc Group (BAHG) to interface with Reclamation and GCMRC in developing a draft TWP, and to help the TWG develop budget recommendations for AMWG consideration.
GCDAMP Strategic Plan
The GCDAMP Strategic Plan (AMPSP) is a long-term plan drafted in August 2001 by GCDAMP and GCMRC participants that identifies the AMWG’s vision, mission, principles, goals, management objectives, information needs, and management actions. 		LTEMP Science Plan
The LTEMP Science Plan describe a strategy by which monitoring and research data in the natural and social sciences will be collected, analyzed, and provided to DOI, its bureaus, and to the GCDAMP in support of implementation of LTEMP. 		Core Monitoring Plan
The GCMRC Core Monitoring Plan (CMP) describes the consistent, long-term, repeated measurements using scientifically accepted protocols to measure status and trends of key resources to answer specific questions. Core monitoring is implemented on a fixed schedule regardless of budget or other circumstances (for example, water year, experimental flows, temperature control, stocking strategy, nonnative control, etc.) affecting target resources. 		Monitoring and Research Plan
The GCMRC Monitoring and Research Plan (MRP) specifies (1) core monitoring activities, (2) research and development activities, and (3) long-term experimental activities consistent with the strategies and priorities established in this SSP to be conducted over the next 5 years to address some of the strategic science questions associated with AMWG priority questions. 		Budget and Work Plan
The GCMRC Triennial Work Plan (TWP) identifies the scope, objectives, and budget for monitoring and research activities planned for a 3-year period. When completed, the TWP will be consistent with the MRP.

Funding the Glen Canyon Dam Adaptive Management Program

PUBLIC LAW 106–377—APPENDIX B 114 STAT. 1441A–68-69: "The Cap Language"
SEC. 204.
(a) IN GENERAL. For fiscal year 2001 and each fiscal year thereafter, the Secretary of the Interior shall continue funding, from power revenues, the activities of the Glen Canyon Dam Adaptive Management Program as authorized by section 1807 of the Grand Canyon Protection Act of 1992 (106 Stat. 4672), at not more than $7,850,000 (October 2000 price level), adjusted in subsequent years to reflect changes in the Consumer Price Index for All Urban Consumers published by the Bureau of Labor Statistics of the Department of Labor.
(b) VOLUNTARY CONTRIBUTIONS. Nothing in this section precludes the use of voluntary financial contributions (except power revenues) to the Adaptive Management Program that may be authorized by law.
(c) ACTIVITIES TO BE FUNDED. The activities to be funded as provided under subsection (a) include activities required to meet the requirements of section 1802(a) and subsections (a) and (b) of section 1805 of the Grand Canyon Protection Act of 1992 (106 Stat. 4672), including the requirements of the Biological Opinion on the Operation of Glen Canyon Dam and activities required by the Programmatic Agreement on Cultural and Historic Properties, to the extent that the requirements and activities are consistent with the Grand Canyon Protection Act of 1992 (106 Stat. 4672).
(d) ADDITIONAL FUNDING. To the extent that funding under subsection (a) is insufficient to pay the costs of the monitoring and research and other activities of the Glen Canyon Dam Adaptive Management Program, the Secretary of the Interior may use funding from other sources, including funds appropriated for that purpose. All such appropriated funds shall be nonreimbursable and nonreturnable.

Experimental Fund

In 2003, the GCDAMP established a fund to pay for experimental research projects so that they can be conducted without financially impacting other aspects of the science program. The current balance of the experimental fund at the end of the FY2007 is anticipated to be approximately $900,000. An additional $500,000 will be set aside by the GCMRC annually in an account at Reclamation to fund the BHBF tests and other research related to experimental efforts. Deposits to the experimental account will cease when the balance reaches $2.5 million.Monitoring and Research Plan, page 8

If the funds allocated to the Experimental Management Fund are not needed in a given year, at the end of the year, they will be transferred to the Native Fish Conservation Contingency Fund (Reclamation project C.6); some year-end experimental management funds may also be allocated to the Contingency Fund for NHPA Section 106 Compliance (Reclamation project D.10). [1]

Native Fish Conservation Contingency Fund

“The goal of this budget item is to ensure that funds are available for native fish conservation actions or nonnative fish control the event this conservation action is needed for endangered humpback chub…”[2]

  • Projected balance at end of FY 17: ~$1,400,000 [3]

New USGS Flagstaff Science Building and Overhead Projection

  • Occupancy agreement between USGS, City of Flagstaff, and GSA signed in April 2019
  • Occupancy start of FY2021 at earliest, overhead may increase some during planning and construction
  • FY2020 overhead on GCDAMP funds: Current projection ~16%, pass-through rate = 3.0%
  • Overhead on GCDAMP funds to ~26% upon occupancy [4]
