SWAMP - 2019 Recreational Beneficial Use Assessments

Since 2007, the Central Valley Water Board has conducted Recreational Beneficial Use Assessments monitoring each summer. Recreation beneficial uses are assessed using E. coli as an indicator of fecal pollution. In 2019, the Central Valley Water Board is conducting weekly sampling in the Lower American River, the Stockton Urban Waterways, and the Upper San Joaquin River.
