SWAMP - Surface Water Ambient Monitoring Program

The statewide monitoring portion of SWAMP is currently not being implemented.

The overall goal of statewide monitoring is to develop a comprehensive statewide picture of status and trends of the quality of California's surface water resources.

This portion of the program was to be implemented in each hydrologic unit (including coastal waters) of the State at least one time every five years, focusing on collecting information on water bodies for which the State presently has little information and on determining the effects of diffuse sources of pollution and the baseline conditions of potentially clean areas.

For inland waters, the program would be implemented using a rotating basin framework where each Region will be divided into five areas consisting of one or more hydrologic unit. The major watercourses and tributaries in these areas would be monitored for a one-year period at least once every five years. In coastal waters, a smaller amount of probabilistic monitoring will be completed.
