Drexel City Reservoir South Nr. Dam vs North Lake

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

Drexel City Reservoir South Nr. Dam and North Lake both received the same overall water quality grade of F (Very Poor). Both are in Wisconsin.

Both Drexel City Reservoir South Nr. Dam and North Lake sit in Missouri. 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 close: Drexel City Reservoir South Nr. Dam (F) and North Lake (F) are within one letter of each other on the LakeGrade rubric. The per-parameter sub-grades below will show where the small differences actually live.

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.

F

Very murky, less than 0.9 ft of visibility.

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

Verdict

Both lakes earn the same Grade F. The tiebreakers come down to clarity (Drexel City Reservoir South Nr. Dam: 0.9 ft, North Lake: 1.6 ft) and what you want from the lake. Drexel City Reservoir South Nr. Dam matches its peer on species count.
