Wisconsin Lakes FAQs

Ranking the Lakes
What makes a lake pristine? Crystal-clear water? Most people think so, and our list of the clearest lakes (below) provides this ranking.
In Wisconsin’s northern glacial lakes, water clarity readings of 30 and 40 feet are common, says Laura Herman of the UW-Extension Lakes Program at UW-Stevens Point. “If we got a 5 foot reading up here, we’d think ‘Holy butt-kiss!' But in the southern part of the state, we’d think that’s OK.”
Northern lakes have an edge because the glaciers dumped most of the topsoil down south. “So there’s less of it left to run into the lakes up north,” says Jeff Thornton, principal environmental planner for the Southeastern Wisconsin Regional Planning Commission.
Meanwhile, in the southern part of the state, runoff of nutrient-rich soil and agricultural fertilizers create algae blooms that diminish water clarity.
The Wisconsin Department of Natural Resources considers 32 feet excellent water clarity; 20 is very good; 10 feet, good; 7 feet, fair; 5 feet, poor; and 3 feet, very poor.
But the clearest lakes aren’t necessarily the healthiest, caution Wisconsin's DNR experts. An extremely clear lake may lack the plant life needed to support a robust fishery. Ecologically balanced lakes are more important: those with a healthy mix of native plants, forested shores, minimum runoff coming into them, a good fishery and diverse wildlife. That’s our healthiest lakes list.
At the other extreme are the murkiest lakes. Dodge County’s Fox Lake “is the most challenged lake in the state,” DNR Lakes and Wetlands Section Chief Jeff Bode says, noting its high phosphorus level and poor native plant community. Farms with 400 and 500 dairy cows dot its watershed and “industrial waste is being spread in its backyard,” he says. The lake underwent a restoration that held for a while, but it has relapsed. “The water is pea-soup-green again,” Bode notes.

The most frequently caught were: panfish, bass, walleye, northern pike, trout, catfish and muskie. In all, 165 species are found in the state.
