North Twin Lake vs South Twin Lake
Water quality, depth, fish species, and recreation comparison.
North Twin Lake and South Twin Lake both received the same overall water quality grade of A (Excellent). Both are in Polk County, Wisconsin.
Both North Twin Lake and South Twin Lake sit in Wisconsin. A same-state comparison strips out the state-level water-quality regime as a variable: any grade differences here are about the lakes themselves, not the agencies grading them. These two are within a letter of each other on the rubric — North Twin Lake (A) versus South Twin Lake (A). The deciding factors for a recreational visitor are likely physical (depth, access, fish species) rather than water-quality differences.
With grades this close, the choice between the two lakes turns on non-water-quality factors: depth, fish species, public access, distance from home. The per-lake pages below cover all of those.

Bold value = better for that metric (lower phosphorus / chlorophyll = cleaner; higher Secchi / depth / species count = better).
Verdict
Both lakes earn the same Grade A. The tiebreakers come down to what you want from the lake. North Twin Lake matches its peer on species count.
