Tecumseh Lake vs Vienna Correctional Center Lake

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

Tecumseh Lake has a higher water quality grade (B, Good) than Vienna Correctional Center Lake (C, Fair). Both are in Wisconsin.

Tecumseh Lake and Vienna Correctional Center Lake are both in Illinois — a same-state head-to-head where the comparison comes down to lake-specific differences in depth, watershed, and monitoring history rather than the broader state-level water-quality regime. These two are within a letter of each other on the rubric — Tecumseh Lake (B) versus Vienna Correctional Center 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.
