Lake of the Oaks vs Poll Miller Park Lake
Water quality, depth, fish species, and recreation comparison.
Lake of the Oaks and Poll Miller Park Lake both received the same overall water quality grade of C (Fair).
Lake of the Oaks is in Missouri; Poll Miller Park Lake is in Iowa. Cross-state comparisons carry an extra wrinkle — Minnesota PCA and Wisconsin DNR use slightly different sampling cadences and station coverage, though both feed the same EPA Water Quality Portal. These two are within a letter of each other on the rubric — Lake of the Oaks (C) versus Poll Miller Park 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.

Bold value = better for that metric (lower phosphorus / chlorophyll = cleaner; higher Secchi / depth / species count = better).
Verdict
Both lakes earn the same Grade C. The tiebreakers come down to what you want from the lake. Lake of the Oaks matches its peer on species count.
