Recreation Compass

If you'd rather browse information for a number of lakes, or can't remember a lake name, then use our Recreation Compass interactive mapping tool. With it, you can zoom in to the part of the state you're interested in and get information by just clicking in a lake. Other shortcuts are provided to help you get to a particular city, lake or park fast.


Please note: not every lake in the state has been surveyed or depth sounded; you may not find the lake in which you are interested. Also, it takes several months before the most recent lake surveys are ready to post on the Web site. Those months are needed to analyze the surveys and update the lake database. We update the LakeFinder as soon as new maps and surveys are available. If you do find inconsistencies, please e-mail the Webmaster at
