The Achievements Report highlights recent accomplishments of the SWAMP and its partners, framing the many projects SWAMP is a part of in the context of their value to the State of California and the public at large. The Achievements Report also describes how monitoring data have been used to answer critical water quality questions pertaining to California’s surface waters and how this information has been conveyed to resource managers and the public. Program activities are organized under the following categories: Monitoring, Assessments, Communication, Comparability, Coordination, and Management Decisions.

Bioaccumulation Monitoring Program

The goal of the Bioaccumulation Monitoring Program is to address the “Fishable” beneficial use through surveys of contaminant concentrations in fish tissue throughout waters of the state. The Bioaccumulation Oversight Group (BOG) serves as the advising body for SWAMP’s fish tissue monitoring program. Sampling occurs on a five-year cycle, rotating between lakes and reservoirs, coastal waters, and rivers and streams. The following reports are currently available:

Perennial Streams Assessment (PSA)
The PSA is an ongoing, long-term statewide survey of the ecological condition of wadeable perennial streams and rivers throughout California. The PSA is funded by SWAMP and other partners, including the USEPA and the Water Boards’ Nonpoint Source program. The PSA collects samples for biological indicators (benthic macroinvertebrates, algae) and chemical constituents (nutrients, major ions, etc.), and conducts habitat assessments (both for in-stream and riparian corridor conditions). The PSA has produced numerous reports and other products, including:

Reference Condition Management Program (RCMP)
The RCMP, funded primarily by SWAMP, is California’s program for establishing and maintaining a network of stream and river “reference sites,” and using this network to establish “reference conditions” for wadeable perennial streams and rivers throughout California. The RCMP plays a central role in developing assessment thresholds for biotic integrity and in establishing biological integrity, and is supplemented by reference programs of several partner agencies, such as the U.S. Forest Service, Tahoe Regional Planning Agency, etc.
