Limitations
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 data inconsistencies, please email the Webmaster at [email protected]. If you have general questions about a lake, please email [email protected].
