Sound Science for Informed Water Quality Management
SWAMP is tasked with assessing water quality in all of California’s surface waters. The program conducts monitoring directly and through collaborative partnerships; and provides numerous information products, all designed to support water resource management in California.
New from SWAMP! The Surface Water Ambient Monitoring Program (SWAMP) is pleased to present the 2013 update to the SWAMP Achievements Report. The Achievements Report highlights recent accomplishments of 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.

Going fishing this summer? Is it a good idea to eat what you catch from your local river, stream or lake: Check it out at
Stream Lore - Look into and learn, and/or teach your kids some local stream lore for summer.
Survey of Sport Fish Contaminants in CA Rivers & Streams - SWAMP released findings from the first-ever statewide survey of contaminants in sport fish from California rivers and streams. The survey, conducted in 2011, analyzed 16 fish species from 63 locations for multiple contaminants, including methylmercury and PCBs.
Survey of Mercury Exposure and Risk in Wildlife in CA Lakes & Reservoirs - A two-year study to collect data on mercury concentrations in grebes and fish in 24 California lakes and reservoirs. The data will be used to develop a tool to translate observed mercury concentrations in fish into estimated mercury concentrations in birds.
California Stream Condition Index (CSCI) - SWAMP's new CSCI was finalized in 2013 and represents the next generation of biological indicator for assessing stream health throughout the state. Unlike previous regionally-based indices, the CSCI was built with a statewide dataset representing the broad range of environmental conditions across California. The CSCI is the basis of the new statewide Biological Integrity Assessment implementation.
Central Coast Healthy Watersheds Project Website - The Central Coast Region is developing a new website for the Healthy Watersheds Project that will host the project's site-specific report cards and water quality data.
This summer - how does recreation at your local beach look? Is the water quality OK for wading or swimming? Check out your nearest ocean beaches and San Francisco Bay area spots at: http://www.mywaterquality.ca.gov/safe_to_swim/
SWAMP is pleased to announce the 2013 California Aquatic Bioassessment Workgroup Videos are now available.
Final Report on Wadeable Streams Bioassessment - Region 8, February 2014
The data collected in the Santa Ana Region and watershed during the 2011 bioassessment sampling events concluded the subset of the proposed sites that were to be collected within the region over a six-year experimental period. These results obtained from 2006 to 2011 will provide information for a detailed analysis of the health of the waters within the region.
New from the State Water Board! The Water Boards has developed a Quality Assurance/Quality Control Website. You may access it at: http://www.waterboards.ca.gov/water_issues/programs/quality_assurance/
From SWAMP Partners: The 2013 CA Aquatic Bioassessment Workgroup (CABW) presentations are now available online. These presentations include a wealth of updated stream macroinvertebrate, watershed health, climate change, and other important and timely information.
From SWAMP Partners: Now Available from the Healthy Streams Partnership: California Integrated Assessment of Watershed Health: A report on the Status and Vulnerability of Watershed Health in California, 2013. Prepared by the Cadmus Group, Inc., and the California Healthy Streams Partnership for the U.S. Environmental Protection Agency. EPA-841-R-14-003. November 2013. 118 pp.
SWAMP has released the program’s first Freshwater Algae Report: (The) Condition of California Perennial, Wadeable Streams Based on Algal Indicators - October 2013. SWAMP's overall algae work can be found at: Freshwater Algae Reports.
SWAMP's Bioaccumulation Oversight Group (BOG) convened a workshop on the issue of freshwater cyanotoxins, to reduce the substantial gap in statewide monitoring efforts related to freshwater cyanotoxins. The Summary Report from this workshop is 'Assessing Cyanotoxins in California Fresh Water Habitats'.
SWAMP Field Methods Course - Now complete with the addition of Module 7: Biological & Physical Assessments
