The depositional history of three freshwater lakes in north central Florida: Brooklyn Lake, Levy's Prairie, and Cowpen Lake The depositional history of three freshwater lakes in north central Florida: Brooklyn Lake, Levy's Prairie, and Cowpen Lake
Florida has approximately 7800 lakes that are heavily concentrated in the north-central part of the state—a mantled karst terrain. Although much research has been conducted in Florida’s lakes, there is not much information on the sedimentary infill. The focus of this research is to define the sedimentary infill of three closely spaced lakes (Brooklyn Lake, Levys Prairie, and Cowpen Lake)...
