Fairy Lake
Todd County, MinnesotaLimited DataOligotrophic
On the LakeGrade scale Fairy Lake grades a B, with clarity at 14.2 ft and phosphorus readings still being added placing it above the Minnesota median.
Trophically, Fairy Lake reads as oligotrophic — nutrient-poor, clear, and ecologically more sensitive to disturbance than richer lakes. A maximum depth of 37 ft puts Fairy Lake in the middle of Minnesota's depth distribution. The lake's 307 acres and 4.2 miles of shoreline put it in the mid-range bucket — large enough for varied use, small enough that watershed inputs reach the whole basin. Fairy Lake ranks 8 of 17 in Todd County — solidly in the upper half of the local distribution.
No invasive species are currently listed at Fairy Lake — the lake remains off the Minnesota infested-waters roster. The fishery includes walleye among the lake's 13 documented species — a notable draw for Minnesota anglers. A documented public access point at Fairy Lake makes the lake usable for shore fishing, paddle craft, and trailered boats. Ice-out has been logged at Fairy Lake more than two dozen times, putting the median around Apr 15 — a useful baseline for tracking climate trends. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.

From the 2024-05-21 survey
Spring trap netting targeting Bluegill and Black Crappie was conducted in May of 2024. Bluegill were assessed to estimate size structures and for comparisons to Area lakes with more restrictive bag limits aimed at improving Bluegill size structure. Additionally, a creel survey was ongoing during this survey along with…
