Elmwood Lake vs Hazel Creek Lk. Lake

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

Hazel Creek Lk. Lake has a higher water quality grade (C, Fair) than Elmwood Lake (F, Very Poor). Both are in Wisconsin.

Elmwood Lake and Hazel Creek Lk. 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. The grades are meaningfully apart: Hazel Creek Lk. Lake grades a C while Elmwood Lake grades a F. 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 — Hazel Creek Lk. 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?
