This report describes the process and products of developing a suite of year-round instream flow recommendations for lower Hobble Creek in Utah County, Utah. This project was undertaken by the Utah Reclamation Mitigation and Conservation Commission (the Commission) as a component of the June Sucker Recovery Implementation Program (JSRIP) 2008 Work Plan (JSRIP 2008). The Commission is a Federal agency established by the Central Utah Project Completion Act (CUPCA [Titles II through VI of Public Law 102-575]). The Commission is responsible for mitigating impacts of the Bonneville Unit of the Central Utah Project (CUP) on fish, wildlife, and related recreation resources. The Commission is required to include in its fish and wildlife mitigation plans measures that it determines will “. . . restore, maintain, or enhance the biological productivity and diversity of natural ecosystems within the State and have substantial potential for providing fish, wildlife, and recreation mitigation and conservation opportunities,” and “. . . be based on, and supported by, the best available scientific knowledge”. 1 The JSRIP is a multi-agency cooperative program established to coordinate and implement recovery actions for June sucker (Chasmistes liorus), an endangered fish native to Utah Lake that historically used tributaries such as Hobble Creek for spawning (JSRIP 2002). The JSRIP attempts to balance June sucker recovery needs with the need to provide for ongoing water development for human needs within the Utah Lake basin
