Green Lake vs Moores Lake

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

Moores Lake has a higher water quality grade (B, Good) than Green Lake (D, Poor). Both are in Wisconsin.

Both Green Lake and Moores Lake sit in North Dakota. 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. The grades are meaningfully apart: Moores Lake grades a B while Green Lake grades a D. That two-letter spread reflects real underlying differences — different watershed inputs, different depth profiles, or different monitoring rigor.

For a recreational visitor, the wider grade gap is decisive — Moores 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

Moores Lake wins on overall water quality with a Grade B versus Green Lake's Grade D. Water clarity: 6.2 ft vs 4.9 ft. For fishing diversity, Moores Lake also leads with 0 species.
