East Sylvia Lake vs Upper Maple Lake
Water quality, depth, fish species, and recreation comparison.
East Sylvia Lake and Upper Maple Lake both received the same overall water quality grade of A (Excellent). Both are in Wright County, Minnesota.
Both East Sylvia Lake and Upper Maple Lake sit in Minnesota. 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: East Sylvia Lake (A) and Upper Maple 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.
