Stony Lake vs Ten Mile Lake
Water quality, depth, fish species, and recreation comparison.
Stony Lake reads lower on nutrients and algae than Ten Mile Lake. Both are in Cass County, Minnesota.
Both Stony Lake and Ten Mile Lake sit in Minnesota. A same-state comparison strips out the state-level water-quality regime as a variable: any differences in the readings here are about the lakes themselves, not the agencies sampling them. These two sit close on their nutrient and algae readings, Stony Lake versus Ten Mile Lake. The deciding factors for a recreational visitor are likely physical (depth, access, fish species) rather than water-quality differences.
With readings 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.
