Potentiometric surface of the Floridan Aquifer, Southwest Florida Water Management District, May 1983

Maps of the potentiometric surface of the Floridan aquifer in west-central Florida are prepared semiannually by the U.S. Geological Survey in cooperation with the Southwest Florida Water Management District. Maps for May and September show, respectively, the potentiometric surface of the normally expected annual low and high water level conditions. This report shows the potentiometric surface of the Floridan aquifer for May 1983. Water level measurements were made during May 16-27. The map represents water level conditions when groundwater withdrawals for agricultural use are high, before the beginning of the summer rainy season. Therefore, the potentiometric surface is near its lowest level for the year. (Lantz-PTT)
