Mille Lacs Lake vs Ml-Seventeen Lake
Water quality, depth, fish species, and recreation comparison.
Mille Lacs Lake has a higher water quality grade (B, Good) than Ml-Seventeen Lake (C, Fair). Both are in Aitkin County, Minnesota.
Both Mille Lacs Lake and Ml-Seventeen 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. These two are within a letter of each other on the rubric — Mille Lacs Lake (B) versus Ml-Seventeen Lake (C). The deciding factors for a recreational visitor are likely physical (depth, access, fish species) rather than water-quality differences.
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.
