SPILLWAY PRE- 2010 INTAKE TOWER 260 FEET DIVERSION TUNNEL
Two Major Problems to Address during FERC Relicensing-1995-2004 Problem 1. Surface currents do not move to the dam, and thus fish passage is not possible under the present conditions as smolts can not find their way out of the reservoir. Problem 2. Deschutes River Discharges from the Project are too warm in the late summer and fall.

Reintroduction Plan • Reintroduction Phase 1 • Complete the SWW and fish passage facilities • Ongoing effort to improve habitat • Initial reintroduction of anadromous fish (fry) • Studies of smolt passage in LBC • Early evaluations of fish in their “new” habitat 50% fish passage through reservoir Yes No • Reintroduction Phase 2 • Pass adults upstream, if reared above PRB • Refine Fish Passage Facilities • Continue habitat improvements • Increased effort to rebuild runs • Study fish and developing runs
