Data show a wealth of information

In its daily work, the district gathers and processes much data. Many of the district’s staff are involved in collecting and analyzing large amounts of information to use as a foundation on which to make informed decisions in managing Florida’s water resources.

The information collected includes rainfall amounts, well levels, and surface water levels and fluctuations. The district shares these data, and the public benefits when local governments use the data to designate areas to protect drinking water supplies. For example, the district’s geographic information system and floodplain mapping are used by local governments when planning land use and development.

Likewise, the data are useful as part of district-developed computer models, such as those that show the groundwater flow system, which provide a better understanding of how water moves underground. These models are used to evaluate the impact of current water use patterns in the district and the long-term water supply potential of the area’s aquifers.
