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.
