Endangered Species
Section 7 of the Endangered Species Act (Act) {16 U.S.C. 1531 et seq.] outlines the procedures for federal interagency cooperation to conserve federally listed species and designated critical habitats. The Act directs that federal agencies should participate in the conservation and recovery of listed threatened and endangered species. In addition, the Act states that each federal agency shall insure that any action they authorize, fund, or carry out is not likely to jeopardize the continued existence of a listed species or result in the destruction or adverse modification of critical habitat. | |

Lahontan Basin Area Office (LBAO) lands consist of habitats for primarily three federally listed species: bald eagle, Lahontan cutthroat trout (LCT), and cui-ui. Bald eagle, listed as threatened, primarily utilizes stretches of the Carson and Truckee rivers as wintering habitat, and there have been occasional single nesting pairs at Lahontan, Boca and Stampede reservoirs. LBAO management actions have little effect on the primarily migratory bald eagle population in the area. | |

Reclamation and the U.S. Fish and Wildlife Service designed and modified an existing fish passage elevator at Pyramid Lake into a lock system to reduce stress and mortality on the migratory fish. Cui-ui and some LCT migrate upstream from Pyramid Lake up into the Truckee River in the spring to spawn. Three miles upstream from the lake, they must pass Reclamation’s Marble Bluff Dam using a fish lock that began operation in 1998. Reclamation and the U.S. Fish and Wildlife Service designed and modified an existing fish passage elevator into a lock system to reduce stress and mortality on the migratory fish. The fish lock has easily passed over 200,000 fish per day, many times the capacity of the replaced fish elevator previously | |

in use. Reclamation also recently constructed a state-of-the-art rock channel fishway at Derby Dam on the Truckee River, allowing fish passage for migrating fish species, including LCT and cui-ui. The fishway is a critically important component in the recovery of LCT and reconnects the riverine ecosystem for the first time in approximately 100 years. click here for larger photo | |
Many of LBAO’s projects affect the two listed fish species. Currently the primary projects with the greatest potential to provide benefits for cui-ui and LCT are the Truckee River Operating Agreement (TROA) and the Desert Terminal Lakes program. TROA contains procedures designed to make more efficient use of existing Truckee River reservoirs, and to provide multiple benefits which include enhanced conditions for cui-ui and LCT. The goal of the Desert Terminal Lakes program is to provide additional water to Pyramid, Walker and Summit lakes. The additional water would improve water quality and thus fish habitat in the affected lakes and rivers. |
