Lory Lake vs North Stanchfield Lake
Water quality, depth, fish species, and recreation comparison.
Lory Lake has a higher water quality grade (C, Fair) than North Stanchfield Lake (F, Very Poor). Both are in Isanti County, Minnesota.
Both Lory Lake and North Stanchfield 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 meaningfully apart: Lory Lake grades a C while North Stanchfield Lake grades a F. 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 — Lory 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?
Lory Lake
Murky, only visible to about 6 ft.
North Stanchfield Lake

Side-by-Side Metrics
| Metric | Lory Lake | North Stanchfield Lake |
|---|---|---|
| Overall Grade | C (Fair) | F (Very Poor) |
| Water Clarity | 6 ft | 2.8 ft |
| Phosphorus | 41 µg/L | 171 µg/L |
| Chlorophyll-a (Algae) | 10.7 µg/L | 50.7 µg/L |
| Maximum Depth | - | - |
| Surface Area | 341 acres | 363 acres |
| Public Access | Unknown | Unknown |
| Fish Species | 1 | 0 |
| Trophic State | eutrophic | eutrophic |
Bold value = better for that metric (lower phosphorus / chlorophyll = cleaner; higher Secchi / depth / species count = better).
Verdict
Lory Lake wins on overall water quality with a Grade C versus North Stanchfield Lake's Grade F. Water clarity: 6 ft vs 2.8 ft. For fishing diversity, Lory Lake also leads with 1 species.
