Kenney Lake
Crow Wing County, MinnesotaLimited DataOligotrophic
Kenney Lake comes in at a B on the grading rubric — a respectable showing for a Minnesota lake of its size and depth.
The lake's low TSI puts it in oligotrophic territory — the cleanest of the four trophic classes, but also the most vulnerable to nutrient-driven shifts. At 55 ft of maximum depth, Kenney Lake stratifies reliably through the summer — the hypolimnion stays cooler and clearer than the surface layer suggests. Kenney Lake covers 109 acres alongside 1.8 miles of shoreline — a mid-sized water that supports a working fishery without being so large that conditions diverge between basins. Within Crow Wing County's 120 graded lakes, Kenney Lake ranks 76 — below the local median, though not at the bottom.
No invasive species are currently listed at Kenney Lake — the lake remains off the Minnesota infested-waters roster. The state fisheries records do not list documented species for Kenney Lake, which usually reflects a lack of formal fisheries survey work rather than an empty lake. The lake lacks a documented public access point, so visitor use is limited. Ice-out has been recorded 5 times at Kenney Lake, with a median around Apr 8. 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.

Top Species by Catch Rate
| Species | Avg CPUE | Avg Weight |
|---|---|---|
| Bluegill | 20.61 | 0.11 lb |
| Tullibee (Cisco) | 8.84 | 1.68 lb |
| Yellow Bass | 8.25 | 0.48 lb |

CPUE = catch per unit effort, averaged across surveys (excludes juvenile shoreline seining). Higher CPUE = more abundant in standardized sampling.
From the 1992-06-18 survey
Bowfin, black crappie and walleye were present in low abundance for the lake class. Tullibee (cisco) was abundant and all other species were found in average numbers for the lake class. Northern pike (5.0/gillnet) was again caught in average numbers (similar to 1971- 6.0/gillnet) after not being sampled in gillnets in…
