Watershed and water quality fact pages
You live in a watershed.
If you live in northeast and east-central Florida, you live in a watershed monitored by the St. Johns River Water Management District. The District designed this Web site to inform residents and scientists about the health of the region’s watersheds.
A watershed is an area that water flows over before flowing into a body of water. This site uses Arc Hydro, a modern mapping and data-modeling technology, to deliver easily understandable information about water quality and watersheds in the District’s service area.
Use the map on this site to explore the 73 watersheds monitored by the District’s Surface Water Quality Monitoring (SWQM) program. See descriptions of each watershed and the water quality information the District collects, such as water acidity, clarity, dissolved oxygen, and temperature. See how powerful geographic information system (GIS) mapping technology was used to put these measurements in the context of population density, geology, rainfall, aquifer recharge, and more.
The watersheds monitored by the SWQM program cover approximately 80 percent of the St. Johns River Water Management District’s area. Other monitoring programs operated by the District cover the remaining areas, which may be represented in future revisions of this Web site. More information about the SWQM program, its history, purpose and methodology, can be found on the page that is accessed through the Methodology tab.
