Trinity River Adaptive Management Working Group (TAMWG)

March 26, 2018: The U.S. Fish and Wildlife Service values the collaborative work with our partners on Trinity River restoration and we remain committed to ensuring their input is fully considered as we move forward. The Department of Interior took a comprehensive review of the Trinity River Adaptive Management Working Group and has reaffirmed their decision to keep the group inactive. We strongly believe we can provide the same level of involvement with our stakeholders as we continue the important restoration work in the watershed. .

The purpose of the Trinity River Restoration Program is to restore the Trinity River basin's fish and wildlife populations to those that existed prior to construction of the Trinity River Diversion and to implement measures to restore fish and wildlife habitat in the basin. The Implementation Plan for the Preferred Alternative of the Trinity River Environmental Impact Statement/Environmental Impact Report established an Adaptive Environmental Assessment and Management (AEAM) organization to design and direct monitoring and restoration activities in the Trinity River Basin and to provide recommendations for flow modifications, if necessary. As part of the AEAM organization, the Working Group provides an opportunity for stakeholders to give policy and management advice about restoration efforts. The Working Group will review and make recommendations that are being considered for implementation by the other parts of the AEAM. Recommendations submitted by the Working Group will be with regard to restoration activities identified as necessary to restore the Trinity River. Included as part of these recommendations is review of policy matters, technical issues, annual flow schedules, and Requests For Proposals (RFP’s) for implementation activities as they relate to achieving restoration goals. Stakeholders will have an opportunity to submit alternative hypotheses (alternative methods and strategies) and/or alternative restoration actions to the Trinity Management Council for consideration.
