The button below launches the Minnesota LakeBrowser - an online, interactive lake water clarity mapping tool with Landsat-derived classifications of lake clarity of more than 10,500 lakes for seven years from 1975 to 2008.

Typically, the Minnesota LakeBrowser is used to find the clarity of any Minnesota lake(s).  To do so, you can either zoom in and out of areas to locate lakes of interest, or simply search lakes by typing a lake name in the "Search" box.

Once you have found a particular lake, you can retrieve more detailed lake water information from the Minnesota Pollution Control Agency (PCA) and Department of Natural Resources (DNR).

Researchers are also mapping water clarity with archived satellite data enabling us to go back into the past and look at historical trends. This type of visual information helps resource managers target problem areas, enables systematic monitoring of inland lakes, and demonstrates the power of satellite remote sensing.

Because we have statewide lake water clarity data for more than one time period, you can also view statistical summaries which compare the average clarities over time by county, ecoregion and for the whole state.
