1988 – purchased by Department of Water Resources

DWR difficulties◦ Water Code § 11258 – DWR must contract with

local agencies◦ KCWA – Program must provide local priority◦ 1991 Farming ceased, endangered species

habitat rapidly developed◦ Water Rights Decision 1630 and endangered

species protection in the Delta


1991 – Zero SWP allocation to Ag. 1993 - DWR “halted all design efforts… …

and developed a revised work plan” that provided “only a minimal program to meet DWR responsibilities” (e.g. weed control and road maintenance).


1994 – Monterey Agreement 1995 – KWB MOU◦ Critical agreement with adjoining entities

1996 – Acquisition by KWBA◦ CC&Rs – KCWA was intermediary in transaction; deed

restrictions provide commitments that facilities will benefit the region

◦ JPA define the rights and responsibilities of participants 1997 – Habitat Conservation Plan approved◦ Critical agreement with wildlife agencies

California Aqueduct (State Water Project)◦ 65% of recharged water◦ Entitlement, interruptible

Kern River◦ 23% of recharged water◦ Flood flows, miscellaneous purchases

Friant – Kern Canal (Central Valley Project)◦ 12% of recharged water◦ Flood flows, surplus (e.g. 215) purchases


70 shallow recharge basins◦ Basins occupy 11 square miles◦ 66 miles of levees, 1.5 million cy of fill

8,70,000 AF stored from 1995 to 1999 450,000 AF recharged in 2011 500,000 AF maximum annual recharge
