George Lake
St. Louis County, MinnesotaOligotrophic
George Lake sits at the top of the Minnesota PCA grading rubric with an A, a mark reached by the cleanest lakes in Minnesota. Clarity, phosphorus, and chlorophyll-a all rate similarly, so there is no obvious single lever to pull on watershed management.
Trophically, George Lake reads as oligotrophic — nutrient-poor, clear, and ecologically more sensitive to disturbance than richer lakes. The lake bottoms out at 18 ft — a moderate depth that supports a warm-water fishery without the year-round cold refuge a deeper basin provides. The lake is compact at 42 acres, with 1.3 miles of shoreline and little volume to buffer nutrient inputs. George Lake ranks 35 of 187 in St. Louis County, putting it in the upper tier of locally monitored lakes.
No invasive species are currently listed at George Lake — the lake remains off the Minnesota infested-waters roster. Bass fishing is part of the appeal: the species list runs to 1, anchored by largemouth and/or smallmouth bass. The lake lacks a documented public access point, so visitor use is limited. Monitoring depth is thin here: the LakeGrade rubric is applied to a small number of sample years, and the grade will be revised as more data accumulates.

1 survey on file from MN DNR Fisheries. Most recent: 1996-07-22 (Standard Survey).
Top Species by Catch Rate
| Species | Avg CPUE | Avg Weight |
|---|---|---|
| Black Crappie | 5.88 | 0.46 lb |
| Northern Pike | 4.31 | 2.06 lb |
| Pumpkinseed | 2.06 | 0.08 lb |
| White Sucker | 0.38 | 3.82 lb |
| Largemouth Bass | 0.25 | 1.43 lb |
CPUE = catch per unit effort, averaged across surveys (excludes juvenile shoreline seining). Higher CPUE = more abundant in standardized sampling.

From the 1996-07-22 survey
George is a small, shallow clear water lake located north of Rollins, MN. The fish community if composed of northern pike, largemouth bass, black crappie, pumpkinseed, white sucker and yellow perch. Results of the 1996 survey indicated very good numbers of black crappie. Average length was 8.8 inches with many…
