Locke Lake vs Peltier Lake
Water quality, depth, fish species, and recreation comparison.
Locke Lake and Peltier Lake both received the same overall water quality grade of F (Very Poor). Both are in Anoka County, Minnesota.
Locke Lake and Peltier 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. These two are within a letter of each other on the rubric — Locke Lake (F) versus Peltier Lake (F). 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.
Locke Lake
Very murky, less than 3 ft of visibility.
Peltier Lake
Very murky, less than 2 ft of visibility.
Side-by-Side Metrics
| Metric | Locke Lake | Peltier Lake |
|---|---|---|
| Overall Grade | F (Very Poor) | F (Very Poor) |
| Water Clarity | 3 ft | 2 ft |
| Phosphorus | 107 µg/L | 381.5 µg/L |
| Chlorophyll-a (Algae) | No data | No data |
| Maximum Depth | - | - |
| Surface Area | 23 acres | 301 acres |
| Public Access | Unknown | Unknown |
| Fish Species | 0 | 1 |
| Trophic State | eutrophic | hypereutrophic |
Bold value = better for that metric (lower phosphorus / chlorophyll = cleaner; higher Secchi / depth / species count = better).
Verdict
Both lakes earn the same Grade F. The tiebreakers come down to clarity (Locke Lake: 3 ft, Peltier Lake: 2 ft) and what you want from the lake. Locke Lake has fewer fish species than Peltier Lake.
