The outflow was 107 ft Is. This re;J.ease rate was maintained with a small loss due to drop in head on the ,e\l8I"VOir until January 10, 1981, when the flow was reduced to 77 ft /,s to slow the dra~ rate due to the small snowpack. The, outflow was reduced f= 77 ft3/s to ' 44 ft3/s on Februa,ry 7 and. ):'educed again to 25 ft3/s on March 6 due to the lack of srow. In April the outflow was based on inflow to the reservoir.
