Secretary’s Designee Direction From the May 18, 2022 Adaptive Management Work Group 

Meeting: Seth Shanahan, TWG Chairperson

 Q&A and discussion (30 minutes) 

On May 18, 2022 the Secretary’s Designee directed Reclamation and GCMRC to work with the TWG 

regarding the following:

• Develop a draft strategic plan to prevent, detect, and respond to cool- and warmwater 

invasive fish establishment below Glen Canyon Dam. The plan should include proposed 

monitoring, specific activities to be considered for prevention and response, along with their 

relative effectiveness, detection thresholds (“triggers”) for action, and conditions for 

discontinuing response activities (e.g. due to success, futility, resource limitations, etc.). 

• Develop 2-4 operational alternatives that could help prevent cool- and warmwater invasive 

fish establishment, while minimizing potential adverse effects to other resources. 

Operational alternatives that are not within the scope of the LTEMP ROD may be proposed, 

but would require additional NEPA, ESA, and NHPA compliance. 

Reclamation, GCMRC and the TWG will report out at the August AMWG meeting on the draft 

strategic plan and operational alternatives, and the AMWG may recommend further action or 

study. 

As a starting point, GCMRC will leverage information and products from existing research and 

monitoring efforts within the GCDAMP, as well as from the Smallmouth Bass Task Force. 

Unspent FY 2022 funds from Reclamation Project C.5, Experimental Management Fund, may be 

utilized to support GCMRC staff time for this effort.
