Crooked Lake vs North Long Lake
Water quality, depth, fish species, and recreation comparison.
Crooked Lake and North Long Lake both received the same overall water quality grade of A (Excellent). Both are in Crow Wing County, Minnesota.
Both Crooked Lake and North Long 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. These two are within a letter of each other on the rubric — Crooked Lake (A) versus North Long Lake (A). 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.

Side-by-Side Metrics
| Metric | Crooked Lake | North Long Lake |
|---|---|---|
| Overall Grade | A (Excellent) | A (Excellent) |
| Water Clarity | 15 ft | 15.1 ft |
| Phosphorus | 10 µg/L | 14 µg/L |
| Chlorophyll-a (Algae) | No data | No data |
| Maximum Depth | 54 ft | 97 ft |
| Surface Area | 905.49 acres | 6.2K acres |
| Public Access | Yes | Yes |

| Trophic State | oligotrophic | mesotrophic |
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 (Crooked Lake: 15 ft, North Long Lake: 15.1 ft) and what you want from the lake. Crooked Lake has fewer fish species than North Long Lake.
