About Arc Hydro

This Web site is made possible by the St. Johns River Water Management District’s (the District) Surface Water Quality Monitoring program and the innovative technology of Arc Hydro.

Arc Hydro was developed by Dr. David Maidment (University of Texas, Austin – Center for Research for Water Resources), in collaboration with several prominent universities (Consortium of Universities for the Advancement of Hydrologic Sciences) and ESRI, as a mapping software for water resource professionals. It generates watershed boundaries based on hydrology, and it allows for geospatial representation of surface water bodies and integration with hydrologic and hydraulic modeling. In short, Arc Hydro allows the District to track the health and behavior of surface water in a way that was previously impossible.

Arc Hydro is based on geographic information system (GIS) software. GIS links comprehensive maps with databases of information collected by the District and other agencies. For GIS metadata, click here.
