Potentiometric surface of the upper Floridan aquifer in central Sumter County, Florida, September 1986

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.

Potentiometric surface of the upper Floridan aquifer in the St. Johns River Water Management District and vicinity, Florida, September 1987

This map shows the potentiometric surface of the Upper Floridan aquifer in the St. Johns River Water Management District and vicinity for September 1987. The Upper Floridan aquifer is the principal source of potable water in the area. Water level measurements were made on approximately 1,000 wells and on several springs. The potentiometric surface is shown mostly by 5-foot contour intervals. The potentiometric surface ranged from 129 feet above sea level in Polk County to 77 feet below sea level in Nassau County. Water levels in most key wells ranged from 0 to 10 feet below in May 1987 levels in response to the lack of recharge from rainfall and an attendant increase in pumpage. Declines of about 0 to 3 feet from May 1987 levels were common in most areas of the district. However, the largest declines from May 1987 levels, as much as 7 to 10 feet, were mostly in well fields along the coastline. Many levels in the district were equal to or lower than the average levels of September 1986.

Potentiometric surface of the upper Floridan Aquifer in central Sumter County, Florida, May 1985

This map presents the potentiometric surface of the Floridan aquifer system in central Sumter County, Florida, for May 1985. The Floridan aquifer system is the principal source of portable water in the area. The focus of the map is the potentiometric surface in the Jumper Creek Canal area. Water-level measurements were made on approximately 60 wells. The potentiometric surface ranged in altitude from more than 90 feet in the southeastern part of the county to less than 35 feet northwest of Lake Panasoffkee in the west-central area. (USGS)

Water-quality monitoring of Lakes Faith, Hope, Charity, and Lucien at Maitland, Florida: April 25 to August 25, 1976

This report is the 17th in a series of data report prepared as part of a hydrologic monitoring program conducted by the U.S. GeOlogical Survey in cooperation with the Florida Department of Transportation. The program was initiated in April 1971 and at that time included monitoring the water quality of Lakes Faith, Hope and Charity and storm runoff entering these lakes. In May 1974, a less comprehensive monitoring program on Lake Lucien was added and a separate bimonthly data report prepared. Beginning in January 1976, the two data reports were combined and since that time have been compiled and transmitted triannually to the Florida Department of Transportation, Florida Department of Environmental Regulation, and to the East Central Florida Regional Planning Council.
