Lower Sacramento River Watershed Surface Water Ambient Monitoring Program

Lower Sacramento River Basin

The plan for monitoring in the lower Sacramento River Basin using 2004/2005 SWAMP funds includes two components: The first and largest component is a watershed-based assessment of water column toxicity in the American River Watershed (HU 514 American River). The focus of this assessment will include investigation of potential aquatic life toxicity associated with various land uses in the American River Watershed above Folsom Lake, including urban, agriculture, and historical mining. The second component includes an investigation of urban impacts to water quality in the Pleasant Grove and Kaseburg Creek Watersheds (HU 519 Valley-American) in western Placer County. The focus of this work includes better characterization of sediment toxicity detected with 2003/2004 SWAMP monitoring funds. The sediment toxicity detected with 2003/2004 monitoring was associated with pyrethroid pesticides.
