FINDINGS OF FACT EBMUD'S NEED FOR ADDITIONAL WATER EBMUD has a need for additional water in drought years to supplement deficiencies in supply from Pardee Reservoir on the Mokelumne River. The quantity of water needed will depend, in large measure, on whether EBr4UD supplies water to the Contra Costa County Water District. Currently EBMUD supplies water to over one million customers in a 300 square- mile area located in Alameda and Contra Costa Counties. EBMUD supplies an average of 204 million gallons per day (mgd) and has an average consumotion of 168 gallons per capita per day. During the extraordinarily severe drought of 1976/1977, EBMUD experienced substantial deficiencies in its water supply. In lg77 EBMLr3 experienced deficiencies of approximately 40%, i.e., sufficient water was available 60~- of the demand. Water needs were met by imposing mandatory cons.=rvation measures and by the diversion of water from the Delta. '- The Board has reviewed a comprehensive study recently completed by ESHU~ to determine its future water requirements. EBHUD estimates that it will n.=e~ 256 mgd in the year 202D to meet water demands within its existing service area. EBhlUD will continue to experience deficencies in supply available from Pardeo Reservoir during future drought years. Computer operational studies completed by EB~UD show that deficiencies will occur about 'once each twelve years. These deficiencies will average about 27 mgd (30,000 AFA). Thus, EBMUD will need to divert about 3D,O00 AF from the American River once every twelve years.
