Wakefield Lake

Aitkin County, MinnesotaLimited DataMesotrophic

Wakefield Lake earns a C — middle-of-the-pack water quality, with one or two parameters dragging the average down from a stronger grade.

Mesotrophic conditions dominate at Wakefield Lake: enough nutrients for a healthy fishery, not so much that algal blooms become a chronic problem. The lake's 69 ft maximum depth is in the upper tier for Minnesota — deep enough for cold-water fish to find refuge in summer. The lake's 164 acres and 3.4 miles of shoreline put it in the mid-range bucket — large enough for varied use, small enough that watershed inputs reach the whole basin. Within Aitkin County's 53 graded lakes, Wakefield Lake ranks 32 — below the local median, though not at the bottom.

No invasive species are currently listed at Wakefield Lake — the lake remains off the Minnesota infested-waters roster. The fishery includes walleye among the lake's 10 documented species — a notable draw for Minnesota anglers. The lake lacks a documented public access point, so visitor use is limited. 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.

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,…
