Shell Lake vs Straight Lake
Water quality, depth, fish species, and recreation comparison.
Straight Lake has a higher water quality grade (B, Good) than Shell Lake (B, Good). Both are in Becker County, Minnesota.
Both Shell Lake and Straight 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: Shell Lake (B) and Straight Lake (B) 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.
Shell Lake
Moderate clarity, visible to about 7.3 ft.
Straight Lake
Moderate clarity, visible to about 8 ft.
Side-by-Side Metrics
| Metric | Shell Lake | Straight Lake |
|---|---|---|
| Overall Grade | B (Good) | B (Good) |
| Water Clarity | 7.3 ft | 8 ft |
| Phosphorus | 22 µg/L | 14 µg/L |
| Chlorophyll-a (Algae) | No data | No data |
| Maximum Depth | 16 ft | 63 ft |
| Surface Area | 3.1K acres | 471.44 acres |
| Public Access | Yes | Yes |
| Fish Species | 1 | 1 |
| Trophic State | mesotrophic | mesotrophic |
Bold value = better for that metric (lower phosphorus / chlorophyll = cleaner; higher Secchi / depth / species count = better).
Verdict
Straight Lake wins on overall water quality with a Grade B versus Shell Lake's Grade B. Water clarity: 8 ft vs 7.3 ft. For fishing diversity, Straight Lake also leads with 1 species.
