“…Hogeye Sink intercepts all or part of the water flowing in Chitty Chatty Creek toward Lake Okahumpka when the potentiometric surface of the Upper Floridan aquifer is below land surface. Hogeye Sink may be a source of water to Lake Okahumpka when the potentiometric surface is above land surface (Simonds and German, 1980). Hogeye Sink is probably hydraulically connected to Fenney Spring (SP18, fig.…”

AbstractA study of Lake Panasoffkee and the surrounding watershed was conducted between October 2005 and September 2009 to gain a better understanding of how this large lake fits within the regional hydrogeologic setting of west-central Florida. Lake Panasoffkee is part of the headwaters of the Withlacoochee River and has a major influence on the hydrology and ecology of that basin. The study defined the interaction between surface water and groundwater, and the magnitude of lake evaporation and groundwater inflow to the lake and how these relate to the Lake Panasoffkee water budget. Geochemical and isotopic analyses were used with water-budget results to describe water sources for the lake. Lake Panasoffkee, the underlying surficial aquifer, and the Floridan aquifer system are hydraulically connected. An area of focused groundwater-discharge potential, where groundwater levels are higher than surface-water levels, is present beneath Lake Panasoffkee and extends several miles northwest and southeast of the lake. Although the size and intensity of the discharge area varied with the seasons and with hydrologic conditions, discharging conditions remained constant throughout the study period.The sandy uplands farther northeast and southeast of Lake Panasoffkee showed the greatest potential for surfacewater to groundwater recharge within the study area. The Lake Panasoffkee watershed lacks a well-developed surface-water drainage system because rainfall rapidly infiltrates the sandy soils in the uplands and recharges the surficial aquifer. The intermediate confining unit is discontinuous in the study area, but even in areas where the confining unit is present, there is a well-developed internal drainage system that compromises the integrity of the unit. The internal drainage system consists of an interconnected network of karst features that includes sinkholes, fissures, and conduits. The discontinuous intermediate confining unit and internal drainage features allow the surficial aquifer to rapidly ...

“…Mean monthly temperatures for the period of record at Bushnell range from approximately 59°F (January) to 81 oF (July, August) (National Climatic Data Center, 1986). The average rainfall at Bushnell is approximately 52 inches, with a distinct wet season from May to September (Simonds and German, 1980).…”
