 At the August 2015 Adaptive Management Work Group (AMWG) meeting the recreational fishing representatives from the International Federation of FlyFishers, Trout Unlimited, and Theodore Roosevelt Conservation Partnership presented the Lees Ferry Recreational Trout Fishery Management Recommendations (Recommendations). Their report provided 15 recommendations for stakeholders to consider. During the meeting, AMWG passed a motion by consensus requesting: The Secretary’s Designee direct Grand Canyon Monitoring and Research Center (GCMRC) to conduct a technical review of the Lees Ferry Recreational Trout Fishery Management Recommendation and report its findings to the TWG, and directs the Technical Work Group (TWG) to evaluate the GCMRC review at their October 2015 meeting, and report its findings to AMWG at its February 2016 meeting. GCMRC provided an initial technical review on six of the Recommendations which were presented to TWG during the October 20-21, 2015 meeting. During the TWG meeting stakeholders asked GCMRC to provide points of clarification on their review of the Recommendations and to provide additional feedback on the remaining nine recommendations. Additionally TWG developed a Trout Ad Hoc Grout (TAHG) to evaluate the GCMRC technical review and provide recommendations to the TWG.
