Camache Reservoir, California

Camanche Reservoir East Bay Municipal Utility District

The East Bay Municipal Utility District (EBMUD) supplies drinking water to 1.2 million people in the Oakland, California metropolitan area from the Mokelumne River watershed. During the 1980s, poor water quality resulted in significant fish kills partially as a result of the presence of hydrogen sulfide in Camanche Reservoir releases to the river. High levels of H2 S in the reservoirs hypolimnion layer occurred during the warmest months and scientists recommended installation of a large-scale hyplimenetic oxygenation system to inject oxygen into the cold, dense layer of water. The ECO2 SuperOxygenation system, operational since 1994, includes a 24 ft. high, 12 ft. diameter cone. The system processes 19 MGD, utilizing 16,000 lbs of oxygen per day to raise the D.O. to 100 mg/l. The highly oxygenated water is discharged through a diffuser line at the bottom of the lake
