Toe Lake
Lake County, MinnesotaLimited DataMesotrophic
The LakeGrade rubric puts Toe Lake at a C: clarity at 7.0 ft, phosphorus readings still being added, and a TSI of 49 signal an intermediate trophic state.
A TSI near 49 places Toe Lake in the mesotrophic band — moderate productivity, with seasonal swings between clearer spring water and richer late-summer conditions. At 95 ft of maximum depth, Toe Lake stratifies reliably through the summer — the hypolimnion stays cooler and clearer than the surface layer suggests. The lake's 122 acres and 4.5 miles of shoreline put it in the mid-range bucket — large enough for varied use, small enough that watershed inputs reach the whole basin. Toe Lake ranks 113 of 142 in Lake County — at the lower end of the locally monitored distribution.
No invasive species are currently listed at Toe Lake — the lake remains off the Minnesota infested-waters roster. The state fisheries records do not list documented species for Toe Lake, which usually reflects a lack of formal fisheries survey work rather than an empty lake. No formal public access is documented at Toe Lake — most use is by shoreline residents and their guests. 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.

DNR Fisheries Survey Summary
2 surveys on file from MN DNR Fisheries. Most recent: 1985-09-08 (Standard Survey).
Top Species by Catch Rate
| Species | Avg CPUE | Avg Weight |
|---|---|---|
| LKW | 18.84 | 0.88 lb |
| White Sucker | 2.54 | 0.54 lb |
| Northern Pike | 1.38 | 7.5 lb |
| Yellow Perch | 0.12 | 0.1 lb |
| Largemouth Bass | 0.12 | 0.1 lb |
CPUE = catch per unit effort, averaged across surveys (excludes juvenile shoreline seining). Higher CPUE = more abundant in standardized sampling.
From the 1985-09-08 survey
Fish populations are dominated by large numbers of small whitefish and smaller, but substantial numbers of big northern pike and small white suckers. Yellow perch and largemouth bass also present.
