Straight Lake vs Two Inlets Lake
Water quality, depth, fish species, and recreation comparison.
Two Inlets Lake has a higher water quality grade (A, Excellent) than Straight Lake (C, Fair). Both are in Becker County, Minnesota.
Straight Lake and Two Inlets 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. The grades are meaningfully apart: Two Inlets Lake grades a A while Straight Lake grades a C. That two-letter spread reflects real underlying differences — different watershed inputs, different depth profiles, or different monitoring rigor.
For a recreational visitor, the wider grade gap is decisive — Two Inlets Lake is the better water-quality choice. For a researcher, the gap is the interesting part: what is different about the two watersheds, and which of those differences is mutable?

Side-by-Side Metrics
| Metric | Straight Lake | Two Inlets Lake |
|---|---|---|
| Overall Grade | C (Fair) | A (Excellent) Better |
| Water Clarity | 8 ft | 9 ft Better |
| Phosphorus | 14.5 µg/L Better | 15.5 µg/L |
| Chlorophyll-a (Algae) | 9.4 µg/L | 6.3 µg/L Better |
| Maximum Depth | 63 ft Better | 60 ft |
| Surface Area | 471 acres | 578 acres |
| Public Access | Yes | Yes |
| Fish Species | 15 | 15 |
| Trophic State | mesotrophic | mesotrophic |
A green ✓ marks the better value for that metric (lower phosphorus / chlorophyll = cleaner; higher Secchi / depth / species count = better). Surface area and trophic state carry no tick — a bigger lake is not a better lake.
