The USGS Water Science Centers monitor current streamflow and water-quality conditions at various sites in the Animas and San Juan River Basins in Colorado, New Mexico, and Utah.
Streamgages at these sites provide continuous data on streamflow and select water-quality constituents including specific conductance, water temperature, pH, and turbidity. In addition, water samples are collected periodically for lab analysis of more constituents at several of the sites.
