Surface Water Ambient Monitoring Program (SWAMP)
Program Description
California Assembly Bill AB 982 (Chapter 495, Statutes of 1999) focused State Water Resources Control Board efforts on developing a comprehensive ambient surface water quality monitoring program: The Surface Water Ambient Monitoring Program (SWAMP) was first established in 2000 to meet that need. The information generated from SWAMP serves two purposes at the State Level: to provide a picture of the overall water quality throughout the State, and to better characterize problem sites and reference conditions, investigated through site-specific monitoring.
Both statewide and regional components are necessary to meet the goals of SWAMP. For more information on the Statewide Program, please use the following link: http://www.waterboards.ca.gov/water_issues/programs/swamp
Contaminants in Fish from California Lakes and Reservoirs: Technical Report on Year One of a Two-Year Screening Study
In 2009 SWAMP released a technical report presenting the results from the first year of a screening survey of contaminant accumulation in fish from California lakes and reservoirs. Following are a table and map summarizing the findings for the Central Valley.

Central Valley Water Board SWAMP Efforts
The Central Valley
Water Board, 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, contains
approximately 75% of the State's irrigated land. Three
major basins have been delineated within this region the Sacramento River, San Joaquin River, and
Tulare Lake Basins. Overall Central Valley Water Board SWAMP goals include evaluating beneficial use protection, sources of potential impairment, and effectiveness of implementation efforts. To maximize resources, all monitoring efforts are coordinated with existing monitoring programs—both internal programs (i.e., TMDL, ILRP, subsurface Ag drainage, etc.) and external programs (i.e., DWR, USGS and University of California and grant funded projects).
