It diverts water into the Truckee Canal that would otherwise enter Pyramid Lake. The canal feeds Lake Lahontan reservoir in the Carson River watershed, where it is used for irrigation.[2] It was the first project of the newly organized U.S. Reclamation Service (known today as the U.S. Bureau of Reclamation), organized by the Reclamation Act of 1902.[3] As a result of the diversion, Winnemucca Lake lost inflow and dried up, and Pyramid Lake lost more than {{convert|80|ft}} in elevation, resulting in the near-extinction of the Lahontan cutthroat trout. The dam is operated by the Truckee-Carson Irrigation District. It was named after the Derby Southern Pacific Railroad station.[4] HistoryThe dam was constructed for the U.S. Bureau of Reclamation following an authorization for construction issued on March 14, 1903. Construction commenced on October 2, 1903 and was completed on May 20, 1905.[5] The project was authorized on March 14, 1903 by Secretary of the Interior Ethan A. Hitchcock. The dam is an original feature of the Newlands Reclamation Project, named after Nevada Congressman Francis Newlands, who sponsored the Reclamation Act. Not surprisingly, a dam in Newlands, Nevada launched the project. It one the first of five projects authorized and built under the Reclamation Act of 1902. With passage of the act, the federal government assumed a major role in designing and constructing large-scale irrigation projects throughout the West. The diversion dam is part of the network of water storage, diversion, and conveyance structures that provides water for irrigating about {{convert|73000|acre}} of farmland in an area that receives less than {{convert|4.5|inch}} of annual precipitation. The dam is not designed for water storage. It is a low {{convert|31|ft}} high concrete structure that diverts water from the Truckee River into the Truckee Canal and then two main project canals, the Southside Main Canal ("V" Line) and the Northside Main Canal ("T" Line).[6] It was listed on the National Register of Historic Places in 1978 as the "Derby Diversion Dam."[1] Environmental impactWater diverted at Derby Dam to farms in Lahontan Valley constitutes as much as three-fourths of the flow of the Truckee River, the largest diversion of water from the Truckee River after it flows from Lake Tahoe.[7] The reduction in flow to Pyramid Lake and the inability of Lahontan cutthroat trout (the "salmon-trout" as described by Frémont) to bypass the dam for spawning eliminated them from Lake Lahontan and it's tributaries and caused the near extinction of the species. But in 1979 a remnant population of the original Pyramid Lake cutthroat trout was discovered in a small brook on Pilot Peak, on the Nevada/Utah border. This population was used to successfully restock Lake Lahontan. See also
