Wynne Lake

Wynne 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 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 52 ft maximum depth is in the upper tier for Minnesota — deep enough for cold-water fish to find refuge in summer. At 279 acres, Wynne Lake fits the Minnesota median for monitored lakes, with 6.2 miles of shoreline. Wynne Lake ranks 61 of 187 in St. Louis County — solidly in the upper half of the local distribution.

No invasive species are currently listed at Wynne Lake — the lake remains off the Minnesota infested-waters roster. The fishery includes walleye alongside the lake's other 10 documented species — a notable draw for Minnesota anglers. A documented public access point at Wynne Lake makes the lake usable for shore fishing, paddle craft, and trailered boats. The lake has a partial ice record — 7 observed ice-outs, centered near Apr 23. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
