Dead Colt Creek Dam Lake vs Lake Lamoure

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

Lake Lamoure has a higher water quality grade (C, Fair) than Dead Colt Creek Dam Lake (F, Very Poor). Both are in Wisconsin.

Both Dead Colt Creek Dam Lake and Lake Lamoure sit in North Dakota. 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: Lake Lamoure grades a C while Dead Colt Creek Dam 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 — Lake Lamoure 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?
