This is a series of annual reports that document Florida hydrologic data gathered by the U.S. Geological Survey. Individual volumes cover particular areas of the state, such as northwest Florida. Topics covered include surface water and ground water.

The purpose of this study is to describe the water resources of the Manasota Basin, to evaluate the adequacy of the hydrologic data network for assessing regional effects of water-resources development, and to propose additional data collection, Specific objectives include: (1) description of the surface-water and ground-water resources, existing and potential water-resources development, and water use; (2) development of maps that delineate water quality in the multizoned aquifer system; and (3) analysis of the current hydrologic data network and recommendations for modification of the network. The description of the area's water resources and the data network evaluation are based on existing data and previously published reports.
