State Water Project

On May 5, 1966, Rosedale entered into a water supply contract with the Kern County Water Agency for 34,900 acre-feet of water from the State Water Project (SWP).  Of the 34,900 acre-feet of water, 29,900 is considered “Firm” and the remaining 5,000 acre-feet is considered “surplus”.  The amount of water delivered to Rosedale from the State Water Project (“SWP”) has been significantly diminished as a result of environmental and legal restrictions on pumping water from the Sacramento-San Joaquin Delta (“Delta”).  As a result, this water supply has been reduced to a long-term average of approximately 60% of the contracted amount.  Rosedale, like other SWP contractors, is obligated to pay for its full contract supply, regardless of the quantity of water received.  This is a significant financial burden upon all SWP contractors.


To have a means for transporting SWP water to Rosedale from the California Aqueduct, Rosedale participated in the construction of the 21-mile long Cross Valley Canal (CVC).  Upon reaching Rosedale, the water supplies are delivered directly to recharge areas for direct replenishment of the underlying groundwater aquifer or to landowners within Rosedale who had access to turnouts on the Goose Lake Slough for direct delivery.  Direct delivery to landowners results in less water being pumped and is considered “in-lieu” recharge.  Rosedale has very limited in-lieu recharge capability and relies almost exclusively upon direct recharge.


The SWP supplies make up approximately 25% of the District’s water supply portfolio.
