Filling the Reservoirs


The Cosumnes River is the source of water for the Community. Th District diverts water into all three storage reservoirs (Calero, Chesbro, Clementia) for the Water Treatment Plants to process into drinking water for community use.

Diversion from the river starts no sooner than November 1st, if flow levels are high enough. Typically river flow from the first storms is allowed to pass by, flushing out the river system of sediment and possible contaminants washed in from roadways and agricultural areas. Our goal is to pump the cleanest water possible while being able to fill our reservoirs to maximum capacity each year. We can pump until May 30th.
