The St. Johns RiverWater Management District (SJRWMD) has been a water-level data provider to the National Groundwater Monitoring Network (NGWMN) since 2020. SJRWMD collects, processes, manages and disseminates hydrologic and meteorological data that are used for consumptive use permitting, water shortage management, establishment of minimum flows and levels, water supply planning and management, environmental protection and restoration projects, and operation of district flood control facilities. The program is staffed and managed by the Bureau of Water Resource Information.

The bureau operates and maintains 1,200 hydrologic monitoring stations throughout the district and processes data from approximately 200 additional sites collected by federal agencies, other districts and local governments, or by the U.S. Geological Survey under contract to the district. More than 16 million measurements are collected, verified, processed and stored each year. These data are disseminated to district staff and are made available on the SJRWMD website.

SJRWMD provides water-level from the unconfined surficial aquifer, the intermediate aquifer/intermediate confining unit, and the Floridan Principal aquifers.
