A May 1985 potentiometric surface map of the Upper Floridan aquifer in west-central Florida depicts the annual low water-level period. Most areas of west-central Florida were experiencing drought conditions and water levels were at or approaching near-record low levels. Water levels in most wells measured in May 1985 were lower than in September 1985. May levels averaged about 5 feet lower than September levels in areas north of latitude 28 degrees 07 ' and about 13 feet lower in southern areas. Generally, water levels in May 1985 averaged about 4 feet lower than May 1984 levels in the north and about 6 feet lower in the south. (USGS)
