Clearwater Lake vs Shepard Mountain Lake Intake

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

Clearwater Lake has a higher water quality grade (C, Fair) than Shepard Mountain Lake Intake (D, Poor). Both are in Wisconsin.

Clearwater Lake and Shepard Mountain Lake Intake 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. The grades are close: Clearwater Lake (C) and Shepard Mountain Lake Intake (D) 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.
