Glendale Lake vs Lake of Egypt

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

Glendale Lake has a higher water quality grade (B, Good) than Lake of Egypt (C, Fair). Both are in Wisconsin.

Glendale Lake and Lake of Egypt 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 — Glendale Lake (B) versus Lake of Egypt (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.
