Alpine Lake vs Sugar Hollow Lake

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

Alpine Lake has a higher water quality grade (A, Excellent) than Sugar Hollow Lake (D, Poor). Both are in Warren County, Wisconsin.

Both Alpine Lake and Sugar Hollow 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 meaningfully apart: Alpine Lake grades a A while Sugar Hollow Lake grades a D. That two-letter spread reflects real underlying differences — different watershed inputs, different depth profiles, or different monitoring rigor.

For a recreational visitor, the wider grade gap is decisive — Alpine Lake is the better water-quality choice. For a researcher, the gap is the interesting part: what is different about the two watersheds, and which of those differences is mutable?

A

Alpine Lake

Warren County, Wisconsin

Good clarity, visible to about 12.6 ft.

D

Sugar Hollow Lake
