Pillager Lake vs Sylvan Lake
Water quality, depth, fish species, and recreation comparison.
Pillager Lake and Sylvan Lake both received the same overall water quality grade of A (Excellent). Both are in Cass County, Minnesota.
Pillager Lake and Sylvan 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: Pillager Lake (A) and Sylvan 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 (Pillager Lake: 15.1 ft, Sylvan Lake: 19.8 ft) and what you want from the lake. Pillager Lake supports more documented fish species.
