Tips and tales about keeping water clean
Shoreline landscaping workshops: April 18 and May 8
In the Land of 10,000 lakes, more and more lakeshore landowners are turning toward natural solutions that combine bio-engineering with deep-rooted, native plants to stabilize the land along the water’s edge while also maintaining connected corridors of habitat for beneficial insects, fish, birds, frogs, turtles, and other kinds of wildlife

In 2020, the MPCA removed Forest Lake, Tanners Lake (Oakdale), Owasso (Roseville/Shoreview), Johanna (Arden Hills) and eight lakes in northern Minnesota from the state’s impaired waters list. This was the first time in Minnesota history that any lake or river recovered from a mercury impairment.

Three variables – water clarity, total phosphorus, and chlorophyll – are combined to create a metric known as a trophic state index.
A few years back, Jerry Spetzman began noticing that the color of the algae samples on a white filter corresponded almost perfectly with the lakes’ overall water quality.

Tanners Lake is part of the Ramsey-Washington Metro Watershed District (RWMWD), and the district has worked hard to improve and protect water quality in the lake over the past 20 years. In fact, Tanners was one of the first lakes in Minnesota to be removed from the state’s impaired waters list (in 2004) after phosphorus levels went down and algae stopped being a problem.
