Maple Lake vs Midlothian Lake

Water quality, depth, fish species, and recreation comparison.

Maple Lake and Midlothian Lake both received the same overall water quality grade of D (Poor). Both are in Cook County, Wisconsin.

Both Maple Lake and Midlothian Lake sit in Illinois. 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 — Maple Lake (D) versus Midlothian Lake (D). 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 D. The tiebreakers come down to clarity (Maple Lake: 5 ft, Midlothian Lake: 1.2 ft) and what you want from the lake. Maple Lake matches its peer on species count.
