Construction of the Derby Dam Fish Screen will restore watershed connectivity and support fish movement along the Truckee River, promoting both the recovery of the federally threatened Lahontan Cutthroat Trout (LCT) as well as fishing and recreation opportunities in Nevada.

Fish passage at Derby Dam has been a priority conservation project for LCT recovery for more than two decades. In 2001, the U.S. Fish and Wildlife Service and Reclamation designed and completed a fish bypass around Derby Dam. Since then, the two agencies have been working to implement the protection portion of the Derby passage improvements. Reclamation selected the horizontal fish screen technology and entered into a cooperative agreement with Farmers Conservation Alliance for the design, construction, and commissioning of the screen. Construction of the Derby Dam Fish Screen (DDFS) Project began in October 2019 and will be complete in Fall 2020.
