Lobster Lake

Lobster Lake comes in at a B on the grading rubric — a respectable showing for a Minnesota lake of its size and depth. The two scored sub-grades — clarity and phosphorus — track close together, so neither one is dragging the average down.

The lake sits in the mesotrophic zone — the band where most well-managed Minnesota lakes fall. Lobster Lake is unusually deep for Minnesota at 65 ft, which buffers the lake against summer warming and helps the deep water stay oxygenated. Lobster Lake covers 1,334 acres alongside 17.3 miles of shoreline, large enough that conditions can vary meaningfully between bays. Lobster Lake ranks 24 of 51 in Douglas County — solidly in the upper half of the local distribution.

Zebra mussel presence at Lobster Lake means the lake's clarity numbers carry an asterisk — filtered water is not the same as nutrient-poor water. Lobster Lake's fishery is anchored by muskellunge, with 18 documented species in total — a destination water for muskie anglers. A documented public access point at Lobster Lake makes the lake usable for shore fishing, paddle craft, and trailered boats. The lake has a partial ice record — 12 observed ice-outs, centered near Apr 21. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
