Crane Lake vs Sand Point Lake
Water quality, depth, fish species, and recreation comparison.
Sand Point Lake has a higher water quality grade (C, Fair) than Crane Lake (D, Poor). Both are in St. Louis County, Minnesota.
Both Crane Lake and Sand Point 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 — Crane Lake (D) versus Sand Point Lake (C). 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.
Crane Lake
Murky, only visible to about 6.6 ft.
Sand Point Lake
Moderate clarity, visible to about 7.5 ft.
Side-by-Side Metrics
| Metric | Crane Lake | Sand Point Lake |
|---|---|---|
| Overall Grade | D (Poor) | C (Fair) |
| Water Clarity | 6.6 ft | 7.5 ft |
| Phosphorus | No data | No data |
| Chlorophyll-a (Algae) | No data | No data |
| Maximum Depth | 80 ft | 184 ft |
| Surface Area | 2.9K acres | 8.5K acres |
| Public Access | Yes | No |
| Fish Species | 1 | 1 |
| Trophic State | eutrophic | mesotrophic |
Bold value = better for that metric (lower phosphorus / chlorophyll = cleaner; higher Secchi / depth / species count = better).
Verdict
Sand Point Lake wins on overall water quality with a Grade C versus Crane Lake's Grade D. Water clarity: 7.5 ft vs 6.6 ft. For fishing diversity, Sand Point Lake also leads with 1 species.
