The attached Decision Notice addresses proposed actions for a project entitled Chadbourne Diversion Repairs and Fish Passage Retrofits. This Yellowstone cutthroat trout conservation project proposes to repair an aging irrigation structure that has had the added benefit of preventing wide-scale invasion of rainbow trout into the Shields River watershed. Built in 1908, the diversion has structural problems and rainbow trout can swim over the diversion at some flows. This project will restore the structural stability of the Chadbourne and add several retrofits that will make it impassable to rainbow trout. The EA included a selective fish passage component, which is no longer part of the project. Two comments were received during a 30-day comment period ending August 10, 2012. This Draft EA is available for review in Helena at FWP’s Headquarters, the State Library, and the Environmental Quality Council. It also may be obtained from FWP at the address provided above, or viewed on FWP’s Internet website: http://www.fwp.mt.gov . It is my decision to proceed with the proposed project, with the exception of the selective fish passage component.
