Find stocking reports
Stocking reports provide access to stocking activity by fish species and/or county. Reports are comprised of information for many lakes and are intended as a summary.
LakeFinder uses data provided by Minnesota Pollution Control Agency (PCA), University of Minnesota (UofMN) and Minnesota Department of Health (MDH).

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 email the Webmaster at [email protected].
