Tetonka Lake vs Upper Sakatah Lake

Water quality, depth, fish species, and recreation comparison.

Tetonka Lake and Upper Sakatah Lake both received the same overall water quality grade of F (Very Poor). Both are in Le Sueur County, Minnesota.

Both Tetonka Lake and Upper Sakatah 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 — Tetonka Lake (F) versus Upper Sakatah Lake (F). 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.

Bold value = better for that metric (lower phosphorus / chlorophyll = cleaner; higher Secchi / depth / species count = better).

Verdict

Both lakes earn the same Grade F. The tiebreakers come down to clarity (Tetonka Lake: 3 ft, Upper Sakatah Lake: 3 ft) and what you want from the lake. Tetonka Lake matches its peer on species count.
