Kego Lake

Crow Wing County, MinnesotaMesotrophic

Kego Lake carries a solid B grade — strong on most parameters, with measurements that hold up well across the summer season. With clarity and phosphorus scored, the sub-grades cluster within a letter of each other, pointing to stable conditions rather than one specific stressor.

Mesotrophic conditions dominate at Kego Lake: enough nutrients for a healthy fishery, not so much that algal blooms become a chronic problem. The lake bottoms out at 20 ft — a moderate depth that supports a warm-water fishery without the year-round cold refuge a deeper basin provides. At 296 acres, Kego Lake fits the Minnesota median for monitored lakes, with 4.2 miles of shoreline. Kego Lake ranks 97 of 120 in Crow Wing County — at the lower end of the locally monitored distribution.

Kego Lake has no invasive species recorded in Minnesota state databases as of 2024, though prevention practices still apply at all access points. Bass fishing is part of the appeal: the species list runs to 12, anchored by largemouth and/or smallmouth bass. A documented public access point at Kego Lake makes the lake usable for shore fishing, paddle craft, and trailered boats. 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.

From the 2024-08-05 survey

A targeted survey of nearshore fish species in Kego Lake was conducted on August 5-6, 2024, by Index of Biological Integrity (IBI) Program staff. Sampling sites were evenly spaced around the lake, and each was sampled by backpack electrofishing and seining with a 50-foot or 15-foot seine, where possible. Backpack…
