Hydrologic data collection program

The hydrologic data collection program of the St. Johns River Water Management District 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 Division of Hydrologic Data Services (HDS).

HDS operates and maintains more than 1,200 monitoring stations throughout the District and processes data from approximately 300 additional sites collected by county and municipal agencies through mutual agreement 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 the public upon request and are readily available on this Web site. HDS also compiles the District’s Hydrologic Conditions Report, which is posted each month on to this Web site.
