Document Description
The California Department of Fish and Wildlife (CDFW) has executed Lake or Streambed Alteration Agreement number EPIMS-MOO-21908-R6 (Agreement), pursuant to section 1602 of the Fish and Game Code to the Project Applicant, Los Angeles Department of Water and Power. The Project is limited to the release of water to the Owens River below the court-ordered average managed baseflows between the Upper Gorge Power Plant and the Control Gorge Power Plant. Flows will be reduced to seepage flows (from Long Valley Reservoir) between the Upper Gorge Power Plant and Control Gorge Power Plant in accordance with Measure 2.1 of the Agreement. The flows will be reduced to seepage flows during a temporary
outage of Tunnel 1 and the associated penstock, so that the Permittee may repair the Upper Gorge Power Plant turbine shut-off valve. The repair work entails disassembling, cleaning, inspecting, testing, refurbishing, and replacing the turbine shut-off valve system components.
