Bathymetric maps, also known as depth contour maps, display the shape and depth of a lake. They are valuable tools for lake managers because they provide information about the area and volume of the lake at certain depths. This information can then be used to determine how much of the lake loses dissolved oxygen in the summer, how much of the lake bottom can be inhabited by plants, and is essential in the application of whole-lake herbicide treatments, harvesting activities and alum treatments.
The Lakes Management Unit (LMU) has created bathymetric maps for many of the larger lakes in the county. However, many relatively small, manmade lakes have never been mapped, and lake managers are carrying out management techniques without adequate information. The LMU recommends the creation of a bathymetric map for all lakes larger than six acres and can provide the names of several companies that can be hired to do the work.
If you are interested in the creation of a bathymetric map of your lake, please contact the Lakes Management Unit at (847) 377-8030. Below are the most current bathymetric maps for many lakes in Lake County.
