Construction of the Derby Dam fish screen will help Reclamation fulfill its mission to provide reliable water in an environmentally sound manner. This project will restore watershed connectivity and support fish movement along the Truckee River and promote the recovery of the federally threatened Lahontan Cutthroat Trout, as well as fishing and recreation opportunities in Nevada.
Two decades of concentrated efforts by the U.S. Fish and Wildlife Service’s Lahontan National Fish Hatchery Complex and Pyramid Lake Paiute Tribe have helped the threatened Lahontan Cutthroat Trout, a fish once thought to be extinct, successfully move from Pyramid Lake, past Derby Dam, to the lower Truckee River for spawning. Installation of the screen will provide substantially improved access to important upstream rearing and spawning habitat for threatened Lahontan Cutthroat Trout for the first time since 1905.
Reclamation entered into a cooperative agreement with Farmers Conservation Alliance (FCA) to design, construct and commission a horizontal fish screen. The horizontally oriented fish screen will work with the diverted flow of water rather than against it, providing consistent fish protection by allowing fish and debris to move above and over the surface of the screen material.
Construction of the screen is expected to be complete in Fall 2020. The construction of Derby Dam, completed in 1905, was one of the first projects of the newly formed U.S. Reclamation Service (now Bureau of Reclamation) organized under the Reclamation Act of 1902. Today, Reclamation oversees infrastructure that delivers water to more than 31 million people and provides one out of five western farmers with irrigation water for 10 million acres of farmland.
