Custer Mine Pond vs Lake Audubon
Water quality, depth, fish species, and recreation comparison.
Lake Audubon has a higher water quality grade (B, Good) than Custer Mine Pond (C, Fair). Both are in McLean County, Wisconsin.
Both Custer Mine Pond and Lake Audubon 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 — Custer Mine Pond (C) versus Lake Audubon (B). 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.
Custer Mine Pond
Very murky, less than 2.2 ft of visibility.

Side-by-Side Metrics
| Metric | Custer Mine Pond | Lake Audubon |
|---|---|---|
| Overall Grade | C (Fair) | B (Good) |
| Water Clarity | 2.2 ft | 4.7 ft |
| Phosphorus | No data | No data |
| Chlorophyll-a (Algae) | 3.3 µg/L | 4.7 µg/L |
| Maximum Depth | - | - |
| Surface Area | 10.7 acres | 19.1K acres |
| Public Access | Unknown | Unknown |
