FY21-23 Triennial Budget and Workplan

Triennial Budget and Work Plan -- Fiscal Years 2021-2023 The Glen Canyon Dam Adaptive Management Program (GCDAMP) is an advisory process wherein protection, management, and improvement of Colorado River resources downstream from Glen Canyon Dam are considered in planning dam operations. The Grand Canyon Protection Act (GCPA) of 1992 directs the Secretary of the Interior (the Secretary) to establish and implement long-term monitoring and research programs to ensure that Glen Canyon Dam is operated “… in such a manner as to protect, mitigate adverse impacts to, and improve the values for which Grand Canyon National Park and Glen Canyon National Recreation Area were established….”. The 1995 Final Environmental Impact Statement (EIS) for Operation of Glen Canyon Dam (U.S. Department of the Interior, 1995) recommended creation of a federal advisory committee to advise the Secretary on adaptive management for operations of the dam. The Record of Decision (ROD) for the 1995 EIS, which was signed in October 1996, created this federal advisory committee. The charter of the Adaptive Management Work Group (AMWG) that implements the GCDAMP was signed in January 1997. Many stakeholders who are members of the AMWG also participate at a technical level in the Technical Work Group (TWG). The TWG formulates recommendations about research and monitoring for consideration by the AMWG. A new Long Term Experimental and Management Plan (LTEMP) EIS was completed in 2016 and an associated ROD was signed on December 15, 2016 (U.S. Department of the Interior, 2016a, b). The LTEMP ROD reaffirms continuation of the GCDAMP, AMWG and TWG and specifies new experimental flow and non-flow actions and compliance requirements for the operations of Glen Canyon Dam until 2037. In fiscal years 2021, 2022, and 2023 (FY2021-23), the GCMRC and its cooperators will continue to undertake monitoring and research activities, as outlined in this Triennial Work Plan (TWP), that will respond to the legal requirements of GCPA and the recently approved LTEMP and will monitor the status and trends of natural, cultural, and recreational resources of the Colorado River between the forebay of Glen Canyon Dam and the western boundary of Grand Canyon National Park. This segment of the Colorado River is administratively termed the Colorado River ecosystem (CRe) which is defined as “the Colorado River mainstem corridor and interacting resources in associated riparian and terrace zones, located primarily from the forebay of Glen Canyon Dam to the western boundary of Grand Canyon National Park...” (US Department of the Interior, 2016a). All activities to be conducted by GCMRC in the CRe for FY2021-23 are described in this TWP. [1]

Long-term Experimental and Management Plan (LTEMP) The LTEMP provides the basis for decisions that identify management actions and experimental options that will provide a framework for adaptively managing Glen Canyon Dam operations over the next 20 years	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 Workplan 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 triennial work plan will be consistent with the MRP.

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. Razorback Sucker Ongoing actions: Larval and small-bodied fish monitoring. Actions to benefit all native aquatic species 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.
