Potentiometric surface of the Floridan aquifer in the Northwest Florida Water Management District, May 1980

A May 1980 potentiometric surface map of the Northwest Florida Water Management District depicts water levels in wells tapping the Floridan aquifer prior to summer pumpage. Compared to earlier potentiometric maps of the area, there are no significant differences in the 1980 map that are the result of hydrologic conditions. The addition of numerous new monitor wells in Jackson, Calhoun, Gadsden, and Liberty Counties, however, permitted refinement or better delineation of contours and a separation of water-bearing zones of the Floridan aquifer in the latter two counties.
