Lake Tibet vs Seven Hills Lake

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

Lake Tibet and Seven Hills Lake both received the same overall water quality grade of D (Poor). Both are in Putnam County, Wisconsin.

Both Lake Tibet and Seven Hills Lake sit in New York. 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 — Lake Tibet (D) versus Seven Hills Lake (D). 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 D. The tiebreakers come down to clarity (Lake Tibet: 3.7 ft, Seven Hills Lake: 4.8 ft) and what you want from the lake. Lake Tibet matches its peer on species count.
