East Solomon Lake vs Willmar Lake

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

East Solomon Lake and Willmar Lake both received the same overall water quality grade of D (Poor). Both are in Kandiyohi County, Minnesota.

Both East Solomon Lake and Willmar Lake sit in Minnesota. 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. The grades are close: East Solomon Lake (D) and Willmar Lake (D) are within one letter of each other on the LakeGrade rubric. The per-parameter sub-grades below will show where the small differences actually live.

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 (East Solomon Lake: 2.6 ft, Willmar Lake: 2 ft) and what you want from the lake. East Solomon Lake matches its peer on species count.
