Big Woods Lake vs Mcknight Lake
Water quality, depth, fish species, and recreation comparison.
Big Woods Lake and Mcknight Lake both received the same overall water quality grade of F (Very Poor). Both are in Carver County, Minnesota.
Big Woods Lake and Mcknight Lake are both in Minnesota — 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. These two are within a letter of each other on the rubric — Big Woods Lake (F) versus Mcknight Lake (F). 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.
Big Woods Lake
Very murky, less than 1 ft of visibility.
Mcknight Lake
Very murky, less than 2.3 ft of visibility.
Side-by-Side Metrics
| Metric | Big Woods Lake | Mcknight Lake |
|---|---|---|
| Overall Grade | F (Very Poor) | F (Very Poor) |
| Water Clarity | 1 ft | 2.3 ft |
| Phosphorus | 210.5 µg/L | 149 µg/L |
| Chlorophyll-a (Algae) | No data | No data |
| Maximum Depth | - | - |
| Surface Area | 31 acres | 31 acres |
| Public Access | Unknown | Unknown |
| Fish Species | 1 | 1 |
| Trophic State | hypereutrophic | hypereutrophic |
Bold value = better for that metric (lower phosphorus / chlorophyll = cleaner; higher Secchi / depth / species count = better).
Verdict
Both lakes earn the same Grade F. The tiebreakers come down to clarity (Big Woods Lake: 1 ft, Mcknight Lake: 2.3 ft) and what you want from the lake. Big Woods Lake matches its peer on species count.
