Minnesota may be the Land of Ten Thousand Lakes, but not all of them are pristine waterways. A number of lakes within the state's boundaries are quite polluted.

In this list, we'll explore some of the dirtiest lakes in the entire state, and explain just how they got that way in the first place.

The Minneapolis/St. Paul Metro is one of the worst offenders in terms of water quality, with several lakes making the list. These include Meuwissen Lake, west of Chaska, Chub Lake, south of Lakeville, Lake Augusta in Mendota Heights, Lake Maria in Wright County, and Hazeltine Lake in Chaska. These results come from a study done by the Metropolitan Council a few years back.

In Southeast Minnesota, Lake Pepin, a naturally occurring lake along the Mississippi River, has long had its issues with pollution, due to high sediment runoff. And Lake Phalen in St. Paul is another waterway that has a history of poor water quality, with years of buildup of PFOS chemicals, also known as "forever chemicals", which mainly come from consumer products used in the kitchen and bathroom.

Other lakes in Greater Minnesota with the same problem of "forever chemicals" plaguing their water include Lake Winona in Alexandria and Wild Rice Lake and Fish Lake, located north of Duluth.

But not all of the Land of Ten Thousand Lakes are in as bad of shape as those listed above. Many Minnesota Lakes are thriving, including Deer Lake, north of Grand Rapids, which was recently named the clearest lake in the entire state.
