These are the latest available contour maps of the lake's bottom. These maps can be used to determine where "holes" (deep spots) exist on the lake bottom. Such areas are often productive for fishing. Learn more about bathymetric maps »

The Lake Region Classification System is a tool used for grouping lakes based on similarities in physiography, geology, soils, hydrology, water chemistry, vegetation, and climate. It was created from a cooperative effort involving the United States Environmental Protection Agency, the Florida Department of Environmental Protection, and researchers at the University of Florida's Department of Fisheries and Aquatic Sciences. There are a total of 47 Lake Region groups. These are used to provide a framework of the different types of lakes in the state so that management plans can be developed for groups of lakes with similar characteristics.

Winter Haven/Lake Henry Ridges (Region 7531)
This upland karst area, 130-170 feet in elevation, has an abundance of small to medium sized lakes. The lakes can be characterized as alkaline, moderately hard-water lakes of relatively high mineral content, and are eutrophic.
