SWP Water Contractors

SWP Water Supply Contracts

The Department of Water Resources administers long-term water supply contracts to 29 local water agencies for water service from the State Water Project. These water supply contracts are central to the SWP's construction and operation. In return for State financing, construction, operation and maintenance of Project facilities, the agencies contractually agree to repay all associated SWP capital and operating costs. Original contracts and their amendments for all water contractors are available in PDF format, on request.

SWP contractors operate under water supply contracts created in the 1960s and amended since. Copies of the amended contracts are available on request.

To provide a convenient reference, consolidated contracts have also been compiled for the contractors, integrating the amendments into the language of the original contract. Consolidated SWP water supply contracts are available in PDF format, on request. Note: the consolidated contracts should not be used in lieu of original contracts and their amendments. 

Notices to State Water Project Contractors

Several times a year we issue Notices to SWP Long-Term Water Supply Contractors (NTCs) that provide key information regarding SWP water allocations, water supply programs, billing information, and other administrative matters. NTCs have been issued since 1996, are public records, and all are available on request.

SWP Table A Allocations

The Table A allocation differs each year and also may change over the course of the year. Beginning with an initial allocation that is based primarily on a conservative dry hydrology, current storage and releases to be made through the year—to meet SWP contractual and regulatory obligations—the allocation may change over winter and through spring to reflect the actual and forecast water supply. This document presents historical Table A allocations from 1996 through 2020 and this document presents allocations from 1967 through 1990. Allocations for other years are available in Bulletin 132.

Below, is a list and contact information for the 29 SWP water supply contractors.
