A map of the September 1993 potentiometric surface of the intermediate aquifer system in west- central Florida depicts water levels for the annual high water-level period. Water levels measured in September 1993 were generally below those reported for September 1992. In 134 wells with paired measurements, the September 1993 level ranged from 4.86 feet below to 5.91 feet above the September 1992 level and averaged 0.59 foot below the September 1992 level. The general decline in water levels during this period was largely the result of below normal rainfall and above average seasonal ground-water withdrawals.
