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

Gunflint Lake and Pike Lake both received the same overall water quality grade of A (Excellent). Both are in Cook County, Minnesota.

Reviewed by LakeQuality Editorial Team · Updated

Gunflint Lake and Pike 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. The grades are close: Gunflint Lake (A) and Pike Lake (A) 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 A. The tiebreakers come down to clarity (Gunflint Lake: 16.5 ft, Pike Lake: 17.4 ft) and what you want from the lake. Gunflint Lake supports more documented fish species.
