Good Lake

Good Lake comes in at a B on the grading rubric — a respectable showing for a Minnesota lake of its size and depth.

Mesotrophic conditions dominate at Good Lake: enough nutrients for a healthy fishery, not so much that algal blooms become a chronic problem. Good Lake is unusually deep for Minnesota at 51 ft, which buffers the lake against summer warming and helps the deep water stay oxygenated. The lake's 175 acres and 3.3 miles of shoreline put it in the mid-range bucket — large enough for varied use, small enough that watershed inputs reach the whole basin. Among the 142 graded lakes in Lake County, Good Lake sits at rank 66, above the county median.

No invasive species are currently listed at Good Lake — the lake remains off the Minnesota infested-waters roster. The fishery includes walleye among the lake's 11 documented species — a notable draw for Minnesota anglers. The lake lacks a documented public access point, so visitor use is limited. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
