ground water research

Lake Barco is an acidic (pH 4.5) well-mixed, oligotrophic seepage lake located within the Ordway-Swisher Biological Station. The lake (11.7 ha) and its topographic basin (81 ha) are in the northern division of the Central Lake District physiographic region of Florida. Due to the thickness of the overlying sediments there is no exposed limestone in the depression that forms the lake. There is very little, if any, surface drainage into Lake Barco. Prior studies have confirmed that virtually all the water inflow to the lake is ground water. The clear dominance of groundwater over surface flow, the location within a Station, availability of groundwater monitor wells, and the abundance of prior studies make Lake Barco an ideal test site for ground water research.
