Clearwater Lake and Horseshoe Lake read the same on nutrients and algae. Both are in Crow Wing County, Minnesota.

Reviewed by LakeQuality Editorial Team · Updated

Clearwater Lake and Horseshoe Lake are both in Minnesota — a same-state head-to-head where the comparison comes down to lake-specific differences in depth, watershed, and monitoring history rather than the broader state-level water-quality regime. These two sit close on the readings, Clearwater Lake versus Horseshoe Lake. The deciding factors for a recreational visitor are likely physical (depth, access, fish species) rather than water-quality differences.

With readings 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.

Clearwater Lake

Crow Wing County, Minnesota

Good clarity, visible to about 13 ft.

Horseshoe Lake

A green ✓ marks the better value for that metric (lower phosphorus / chlorophyll = cleaner; higher Secchi / depth / species count = better). Surface area and trophic state carry no tick — a bigger lake is not a better lake.

Verdict

Both lakes earn the same Grade A. The tiebreakers come down to clarity (Clearwater Lake: 13 ft, Horseshoe Lake: 14.4 ft) and what you want from the lake. Clearwater Lake supports more documented fish species.
