This map shows the potentiometric surface of the Upper Floridan aquifer in central Sumter County, Florida, for September 1986. The Upper Floridan aquifer is the principal source of potable water in the area. The focus of the map is in the Jumper Creek Canal area where mine pumpage affects water levels. Water levels rose approximately 2 to 3 feet in the southern part of the study area between May and September but remained stable in the northern part. The potentiometric surface ranged in altitude from more than 90 ft in the southeastern part of the county to less than 40 feet northwest of Lake Panasoffkee in the west-central area. (USGS)
