The lake association wants to reduce the level of phosphorus, which leads to growth of algae and invasive pondweed. It hopes the taconite experiment will do the trick.

Lawsuit: MPCA allows pollution of lakes

The Minnesota Pollution Control Agency for more than a decade has allowed a sewage treatment plant to pollute recreational lakes in Alexandria, an environmental law firm alleges in a new lawsuit.

The Minnesota Pollution Control Agency is placing 500 additional lakes and sections of rivers on its list of impaired waters. Minnesota now has more than 3,600 bodies of water on the list. MPR reports about 40 percent of the state's waters are considered to have an excess of nitrogen, phosphorus, mercury, bacteria or other pollutants. Hundreds of clean-up plans have been developed over the past two decades, but less than 20 bodies of water have come of the list.
