The Derby Dam Horizontal Fish Screen Project has received an Award of Merit in the Water/Environment category from Engineering News-Record (ENR) Southwest 2021 Best Projects competition.

The ENR Southwest Best Projects competition honors the best construction projects of the year located throughout Arizona, Nevada, and New Mexico, as well as the companies responsible for their design and construction. Industry leaders in design and construction judge the projects based on safety, innovation, and teamwork, among other criteria. All winning project teams will be celebrated at an awards ceremony in Phoenix, AZ on November 11, 2021.

The Derby Dam Horizontal Fish Screen Project was designed to improve efficiency for water delivery and fish habitat on the Truckee River. One of the biggest benefits of the fish screen is its impact on fish habitat. The ultimate goal is to allow the Lahontan Cutthroat Trout to move up and down the Truckee River to its historic spawning grounds.

The screens allow the water to drop down below. While most of the water from the structure goes into the canal, the fish are separated and sent through a wide pipe downstream in the Truckee River. The fish use a ladder system to get upstream, past the dam. The Lahontan Cutthroat Trout was once thought to be extinct, but the species has made a comeback, thanks to Pyramid Lake Fisheries.

Congratulations to the project team, Bureau of Reclamation, Farmers Conservation Alliance, McMillen Jacobs, and Granite Construction for the outstanding design, construction, and commission of North America’s largest horizontal fish screen!
