Jordan Lake

Jordan 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 Jordan Lake: enough nutrients for a healthy fishery, not so much that algal blooms become a chronic problem. Jordan Lake is unusually deep for Minnesota at 66 ft, which buffers the lake against summer warming and helps the deep water stay oxygenated. Jordan Lake covers 142 acres alongside 6.2 miles of shoreline — a mid-sized water that supports a working fishery without being so large that conditions diverge between basins. Within Lake County's 142 graded waters, Jordan Lake sits at rank 34, near the top of the local distribution.

No invasive species are currently listed at Jordan Lake — the lake remains off the Minnesota infested-waters roster. The state fisheries records do not list documented species for Jordan Lake, which usually reflects a lack of formal fisheries survey work rather than an empty lake. No formal public access is documented at Jordan 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.
