Lake Marie vs Nine Eagles Lake
Water quality, depth, fish species, and recreation comparison.
Nine Eagles Lake has a higher water quality grade (A, Excellent) than Lake Marie (B, Good).
Lake Marie is in Missouri; Nine Eagles Lake is in Iowa. Cross-state comparisons carry an extra wrinkle — Minnesota PCA and Wisconsin DNR use slightly different sampling cadences and station coverage, though both feed the same EPA Water Quality Portal. The grades are close: Lake Marie (B) and Nine Eagles 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.
