District works to strike Pickerel Lake off impaired waters list
It is not the A-list, but the delist that Shell Rock River Watershed District is working toward for Pickerel Lake.
According to the Minnesota Pollution Control Agency’s 2018 proposed impaired waters list, Pickerel Lake has been listed twice: more recently, in 2016, for aquatic consumption due to mercury in fish tissue, but before that, back in 2008, it was listed for aquatic recreation due to nutrient/eutrophication biological indicators.
