Harmon Lake vs Nygren Dam Lake
Water quality, depth, fish species, and recreation comparison.
Nygren Dam Lake has a higher water quality grade (D, Poor) than Harmon Lake (F, Very Poor). Both are in Morton County, Wisconsin.
Both Harmon Lake and Nygren Dam Lake 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. These two are within a letter of each other on the rubric — Harmon Lake (F) versus Nygren Dam Lake (D). The deciding factors for a recreational visitor are likely physical (depth, access, fish species) rather than water-quality differences.
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.

Side-by-Side Metrics
| Metric | Harmon Lake | Nygren Dam Lake |
|---|---|---|
