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.
