Leavitt Lake
Cass County, MinnesotaMesotrophic
On the LakeGrade scale Leavitt Lake grades a B, with clarity at 8.4 ft and 19 µg/L of phosphorus placing it above the Minnesota median. The lake's weakest score is on Secchi depth — the water looks more turbid than its phosphorus number alone would predict.
The lake sits in the mesotrophic zone — the band where most well-managed Minnesota lakes fall. The lake's 60 ft maximum depth is in the upper tier for Minnesota — deep enough for cold-water fish to find refuge in summer. At 122 acres, Leavitt Lake fits the Minnesota median for monitored lakes, with 3.8 miles of shoreline. Leavitt Lake sits at rank 98 of 133 in Cass County, in the lower half of the local distribution.
Leavitt Lake has no invasive species recorded in Minnesota state databases as of 2024, though prevention practices still apply at all access points. Leavitt Lake's fishery is anchored by muskellunge, with 15 documented species in total — a destination water for muskie anglers. A documented public access point at Leavitt Lake makes the lake usable for shore fishing, paddle craft, and trailered boats. 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.

From the 2023-07-05 survey
A targeted survey of nearshore fish species in Leavitt Lake was conducted on July 5-6, 2023, by Index of Biological Integrity (IBI) Program staff. Sampling sites were evenly spaced around the lake, and each was sampled by backpack electrofishing and seining with a 50-foot seine. Nearshore sampling captured fourteen…
