As a result, the state of California under Governor Jerry Brown (who also objected to New Melones on economic grounds) issued a temporary limit in November 1980 to keep the lake level below Parrott's Ferry Bridge, which marked the lower end of the Stanislaus whitewater. The California Department of Water Resources questioned whether the extra irrigation water was even necessary, and studies by the state Department of Fish and Wildlife suggested that the dam would harm the fisheries it was intended to protect. The state and environmentalists agreed to compromise the lake level at 26 percent of its design capacity, which hydrological studies determined was the optimal volume for fulfilling demands along the Stanislaus without losing too much water to evaporation and flood releases.
