Kota Ray Dam Lake vs Mcleod Reservoir

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

Kota Ray Dam Lake has a higher water quality grade (B, Good) than Mcleod Reservoir (C, Fair). Both are in Williams County, Wisconsin.

Kota Ray Dam Lake and Mcleod Reservoir are both in North Dakota — 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 — Kota Ray Dam Lake (B) versus Mcleod Reservoir (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.
