Lake of the Hills vs Lost Grove Lake

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

Lake of the Hills and Lost Grove Lake both received the same overall water quality grade of C (Fair). Both are in Scott County, Wisconsin.

Both Lake of the Hills and Lost 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. These two are within a letter of each other on the rubric — Lake of the Hills (C) versus Lost Grove Lake (C). 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 C. The tiebreakers come down to clarity (Lake of the Hills: 5.1 ft, Lost Grove Lake: 3.9 ft) and what you want from the lake. Lake of the Hills matches its peer on species count.
