Hydrogeologic Setting and Preliminary Data Analysis for the Hydrologic-BudgetAssessment of Lake Barco, an Acidic Seepage Lake in Putnam County, Florida

摘要

Lake Barco is an acidic seepage lake in north-central Florida. To betterunderstand the mechanisms controlling the acid neutralizing capacity in the lake, a study was initiated to quantify the hydrologic and solute budgets of the lake. Geologic data were evaluated to determine the local hydrogeology and the structural framework of the lake. Climatic and hydrologic data that were required to determine the hydrologic budget of Lake Barco were collected between May 1989 and December 1990. These data include daily climatic variables for computing lake evaporation by the energy-budget and mass-transfer methods. Lake stage and the vertical and areal hydraulic head distribution in the aquifers around the lake were measured starting in September 1988 and were used to describe the ground-water flow patterns around Lake Barco.
