Birch Lake vs Birch Lake

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

Birch Lake has a higher water quality grade (C, Fair) than Birch Lake (D, Poor). Both are in Wisconsin.

Both Birch Lake and Birch Lake sit in Wisconsin. 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 — Birch Lake (D) versus Birch 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.

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

Verdict

Birch Lake wins on overall water quality with a Grade C versus Birch Lake's Grade D. For fishing diversity, Birch Lake also leads with 0 species.
