Surface Water Ambient Monitoring Program (SWAMP)
Statewide SWAMP Program
California Assembly Bill AB 982 (Chapter 495, Statutes of 1999) focuses State Water Resources Control Board (SWRCB) efforts on developing a comprehensive ambient surface water quality monitoring program. The information generated from the SWAMP program will serve two purposes at the State Level: it will provide a picture of the overall water quality throughout the State, and will better characterize problem sites and reference conditions, investigated through site-specific monitoring.
While both statewide and regional components are necessary to meet the goals of the SWAMP program, the consensus of State and Regional Board monitoring coordinators, who meet regularly as the Water Quality Monitoring Coordinating Committee, has been that current funding is not sufficient to adequately address both components independently. Until funding levels increase, each Regional Board will use their available resources to address water quality issues of greatest importance to the Region.

Central Valley RWQCB SWAMP Efforts
Region 5, the Central Valley
Region, covers 40% of the State and stretches from the
Oregon border to the northern tip of Los Angeles County
(60,000 square miles). This area, which includes all
or part of 38 of the State's 53 counties, also contains
approximately 75% of the State's irrigated land. Three
major basins have been delineated within this region,
namely the Sacramento River, San Joaquin River, and
Tulare Lake Basins. SWAMP efforts within each of the
Basins has been developed to maximize monitoring frameworks
already in place and leverage available resources. In
general: the Upper Sacramento River Basin augmented
monitoring efforts by local watershed groups; the Lower
Sacramento River Basin focused initial efforts on special
studies evaluating effluent dominated water bodies with
broader monitoring to follow; the San Joaquin River
Basin built its monitoring effort off of the existing
framework utilized in the Grassland Bypass Project;
and the Tulare Lake Basin focused on watersheds with
known water quality impairments. For more detailed information
