Pleasant Lake vs Webb Lake
Water quality, depth, fish species, and recreation comparison.
Pleasant Lake and Webb Lake both received the same overall water quality grade of A (Excellent). Both are in Cass County, Minnesota.
Both Pleasant Lake and Webb Lake sit in Minnesota. 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 close: Pleasant Lake (A) and Webb Lake (A) are within one letter of each other on the LakeGrade rubric. The per-parameter sub-grades below will show where the small differences actually live.
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.
Pleasant Lake
Crystal clear, you can see 15.5 ft down.
Webb Lake
Crystal clear, you can see 18 ft down.
Side-by-Side Metrics
| Metric | Pleasant Lake | Webb Lake |
|---|---|---|
| Overall Grade | A (Excellent) | A (Excellent) |
| Water Clarity | 15.5 ft | 18 ft |
| Phosphorus | 10 µg/L | 9.5 µg/L |
| Chlorophyll-a (Algae) | 3.1 µg/L | 2.9 µg/L |
| Maximum Depth | 72 ft | 84 ft |
| Surface Area | 1,099 acres | 720 acres |
| Public Access | Yes | Yes |
| Fish Species | 15 | 12 |
| Trophic State | oligotrophic | oligotrophic |
Bold value = better for that metric (lower phosphorus / chlorophyll = cleaner; higher Secchi / depth / species count = better).
Verdict
Both lakes earn the same Grade A. The tiebreakers come down to clarity (Pleasant Lake: 15.5 ft, Webb Lake: 18 ft) and what you want from the lake. Pleasant Lake supports more documented fish species.
