Lpinelk 3 Lake vs Union Grove Lake

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

Lpinelk 3 Lake and Union Grove Lake both received the same overall water quality grade of F (Very Poor). Both are in Wisconsin.

Both Lpinelk 3 Lake and Union Grove Lake sit in Iowa. 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: Lpinelk 3 Lake (F) and Union Grove Lake (F) 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 F. The tiebreakers come down to clarity (Lpinelk 3 Lake: 0.9 ft, Union Grove Lake: 1.6 ft) and what you want from the lake. Lpinelk 3 Lake matches its peer on species count.
