The surficial aquifer is thickest along the Lake Wales Ridge, especially near the southernmost part of the county. At well ROMP 14, located near Hicoria, the surficial aquifer is about 350 ft thick (Clayton, 1998). The hydraulic properties of the surficial aquifer vary considerably and are largely dependent upon aquifer thickness, physical characteristics (such as grain-size and sorting), and the types of material that compose the aquifer. Few data are available on the hydraulic characteristics of the surficial aquifer in Highlands County. Transmissivity estimates from four wells in the county range from 2,400 to 16,300 ft 2/d (Clayton, 1998; DeWitt, 1998; Baldini and Ruppuhn, 1999; Southwest Florida Water Management District, 2000; and Mallams and Lee, 2005) (fig. 19). However, all four wells are located on the Lake Wales Ridge where the aquifer is thick and transmissivities are generally high. Transmissivity values range from 8 to 2,400 ft 2/d in Polk County (Spechler and Kroening, 2007) and from 14 to 5,300 ft 2/d in Hardee and DeSoto Counties (Seaburn and Robertson, 1979; Southwest Florida Water Management District, 2000; LaRoche, 2007).

Horizontal hydraulic conductivities determined for 20 wells along the Kissimmee River in both Highlands and Okeechobee Counties range from 0.8 to 27 ft/d (Jose Valdes, South Florida Water Management District, written commun., 2007). Horizontal hydraulic conductivity values from six wells in Polk County range from 0.3 to 55 ft/d (Southwest Florida Water Management District, 2000). Additional horizontal hydraulic conductivity values reported for wells in adjacent Hardee and DeSoto Counties range from about 1 to 102 ft/d (Southwest Florida Water Management District, 2000; LaRoche, 2007). The altitude of the water levels in wells open to the surficial aquifer represents the water-table level. The water table is not a flat surface, but instead, a sloping surface that may resemble hills and valleys similar to land surface. The depth below land surface to the water table in the surficial aquifer varies from one physiographic region to another. In upland areas, the water table generally is a subdued reflection of land-surface topography. Depths ranging from 10 to 40 ft ? ? ?
