LTEMP BiOp Conservation Measures [1] (2016)
|
Ongoing actions:
- Translocations of humpback chub into tributaries of the Colorado River in Marble and Grand Canyons
- Spring and fall humpback chub population estimate
- Control or removal of nonnative fish in tributaries prior to chub translocations
- Humpback chub refuge population at a federal hatchery
- Ensure that a stable or upward trend of humpback chub mainstem aggregations can be achieved by:
- Annual monitoring of the Little Colorado River humpback chub aggregation (e.g., juvenile chub monitoring parameters).
- Annual monitoring in the mainstem Colorado River to determine status and trends of humpback chub.
- Periodic surveys to identify additional aggregations and individual humpback chub.
- Evaluate existing aggregations and determining drivers of these aggregations.
- Explore means of expanding humpback chub populations outside of the Little Colorado River Inflow aggregation.
- Disease and parasite monitoring
New actions:
- Feasibility study for translocation of humpback chub into Upper Havasu Creek (above Beaver Falls).
- Evaluate other tributaries for potential translocations.
Ongoing actions:
- Larval and small-bodied fish monitoring.
Ongoing actions:
- Investigate the possibility of renovating Bright Angel and Shinumo Creeks with a chemical piscicide.
- Remove brown trout (and other nonnative species) from Bright Angel Creek and the Bright Angel Creek Inflow reach of the Colorado River, and from other areas where new or expanded spawning populations develop.
New actions:
- Explore the efficacy of a temperature control device at the dam to respond to potential extremes in hydrological conditions due to climate conditions that could result in nonnative fish establishment.
- Preventing the passage of deleterious invasive nonnative fish through Glen Canyon Dam.
- Fund the NPS and GCMRC on the completion of planning and compliance to alter the backwater slough at River Mile (RM) 12.
- Develop a plan for implementing rapid response control efforts for newly establishing or existing deleterious invasive nonnative species.
- Experimental use of TMFs to inhibit brown trout spawning and recruitment in Glen Canyon
Southwestern willow flycatcher and Yuma Ridgway’s rail
- Conduct Yuma Ridgway’s rail surveys
- Conduct southwestern willow flycatcher surveys

TWG Budget Preliminary List Exercise
|
The Technical Work Group (TWG) at its January 27, 2017 meeting identified a preliminary list of budget items that it wanted to be considered in the FY 18-20 TWP.
Hot Topics:
- Humpback chub in Western Grand Canyon
- Invasive species surveillance and response (brown trout and green sunfish in Glen Canyon)
- Foodbase Augmentation
- Nutrients
- Synthesis of TEK and indigenous knowledge systems and integrate into AMP
- Hualapai Archive Project
- Arch site and terrace monitoring in Glen Canyon Reach
- Integration of tribal value and knowledge into treatment of archaeological sites
- Cool water TCD and generation on the bypass tubes
- Experiments that could increase hydropower value
- Impacts of TMFs
- HFE monitoring
- Study how lower down ramping rates of HFEs relates to slower eroding beaches via building lower sloping beaches
- Re-evaluate triggers for spring HFEs to include biological considerations as well as sediment
- TWP Chapter 2 to represent the Strategic Science Plan
