Fish Lake vs Lory Lake

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

Lory Lake has a higher water quality grade (C, Fair) than Fish Lake (F, Very Poor). Both are in Minnesota.

Fish Lake and Lory Lake are both in Minnesota — 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. Lory Lake (C) is materially cleaner than Fish Lake (F). A gap that wide is unlikely to close in a single year of remediation work; it reflects multi-decade differences in the lakes themselves.

For a recreational visitor, the wider grade gap is decisive — Lory Lake is the better water-quality choice. For a researcher, the gap is the interesting part: what is different about the two watersheds, and which of those differences is mutable?

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

Verdict

Lory Lake wins on overall water quality with a Grade C versus Fish Lake's Grade F. Water clarity: 6 ft vs 2 ft. For fishing diversity, Lory Lake also leads with 1 species.
