Hamilton Lake vs Jamesport City Lake

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

Hamilton Lake and Jamesport City Lake both received the same overall water quality grade of D (Poor). Both are in Wisconsin.

Hamilton Lake and Jamesport City Lake are both in Missouri — 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 — Hamilton Lake (D) versus Jamesport City Lake (D). 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 D. The tiebreakers come down to what you want from the lake. Hamilton Lake matches its peer on species count.
