Review of the St. Johns River Water Supply Impact Study: Report 1 (2009)

The water use data management program of the St. Johns River Water Management District was established in 1992. Data are collected from primary and secondary sources, verified and analyzed, and made available for general use.

Partnerships have been established with state and local governments and major water users throughout the district for data collection and for sharing and analyzing the data. The focus of the program has been establishing methodologies for making reliable, current water use estimates and future water demand projections. Numerous relational and spatial data sets have been developed to support water demand estimates and projections, the most important of which relate to population, public supply water use, and the location of public supply wells and water service area boundaries. Information generated from these data sets is used for regional groundwater modeling and water supply planning.
