PacifiCorp August 5, 2021 Mr. Jared Bottcher, Acting Area Manager Klamath Basin Area Office Bureau of Reclamation 6600 Washburn Way Klamath Falls, OR 97603-9365 Letter PacifiCorp to Bureau of Reclamation: Request for PacifiCorp Temporary Water Borrow for Tule Lake Sump 1B Dear Mr. Bottcher: PacifiCorp received your letter requesting that we modify operations of the Klamath Hydroelectric Project to allow the diversion of water from Keno Reservoir to support water surface elevations in Tule Lake Sump 1B. The goal of this effort is to provide water into Sump 1B to protect endangered Lost River and Shortnose suckers in Sump 1B and improve conditions for migratory waterfowl that rely on that habitat. PacifiCorp recognizes the challenges the 2021 water year has brought to the Klamath Basin and is happy to make adjustments to how we operate our hydroelectric project to help balance the many competing demands for water. This water will be made available by reducing discharge from Keno Dam by 150 cfs while maintaining normal water surface elevations in Keno Reservoir allowing diversion of water from the Lost River Diversion Channel. At the same time, PacifiCorp will provide 150 cfs from reservoir storage to support minimum flows in the Klamath River downstream of Iron Gate Dam. We understand that our reservoirs will operate at lower-than-normal elevations until water is returned from Lost River flows after the irrigation season. PacifiCorp understands that Reclamation will return water to PacifiCorp's reservoirs following the end of the irrigation season in the Lost River in late September or early October. PacifiCorp is developing operational plans for this action and will coordinate with your staff as that schedule is finalized and throughout the action to make changes as necessary. PacifiCorp appreciates the close collaboration between our organizations regarding the implementation of Klamath River flow releases to support listed species while meeting our other respective obligations and operational objectives.
