In the map below, the black dots represent the 73 water quality monitoring sites of the Surface Water Quality Monitoring (SWQM) program of the St. Johns River Water Management District (the District). As you place your mouse arrow over a point, the Arc Hydro-generated watershed will become visible as a red outline and the site’s project name, as well as the water body’s common name, will pop up. You can use the navigation arrows on the map to zoom in or out—zooming in will be especially helpful for some of the smaller watersheds. You can also locate the watersheds by county or by water body common name using the links below.

More information about the District’s SWQM program, its history, purpose, and methodology, can be found on the page that is accessed through the Methodology tab.
