Rabbit Lake
Aitkin County, MinnesotaLimited DataMesotrophic
Rabbit Lake earns a C — middle-of-the-pack water quality, with one or two parameters dragging the average down from a stronger grade. Sub-grades cluster within a single letter of each other, which usually means the lake is in stable trophic balance rather than fighting one specific stressor.
The lake sits in the mesotrophic zone — the band where most well-managed Minnesota lakes fall. At 51 ft of maximum depth, Rabbit Lake stratifies reliably through the summer — the hypolimnion stays cooler and clearer than the surface layer suggests. Rabbit Lake covers 212 acres alongside 4.6 miles of shoreline — a mid-sized water that supports a working fishery without being so large that conditions diverge between basins. Within Aitkin County's 53 graded lakes, Rabbit Lake ranks 30 — below the local median, though not at the bottom.
No invasive species are currently listed at Rabbit Lake — the lake remains off the Minnesota infested-waters roster. The fishery includes walleye alongside the lake's other 13 documented species — a notable draw for Minnesota anglers. A documented public access point at Rabbit Lake makes the lake usable for shore fishing, paddle craft, and trailered boats. Ice-out has been recorded 17 times at Rabbit Lake, with a median around Apr 14. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.

From the 2025-05-27 survey
Daytime electrofishing was carried out on 5/27/2025 at Rabbit Lake to monitor the Largemouth Bass population. This was the first time Largemouth Bass have been targeted on Rabbit Lake during an electrofishing survey. Two netters were used, and sampling occurred for 2 hours. A total of 68 Largemouth Bass were captured,…
