Cable Lake

Cable Lake carries a solid B grade — strong on most parameters, with measurements that hold up well across the summer season. Clarity, phosphorus, and chlorophyll-a all rate similarly, so there is no obvious single lever to pull on watershed management.

A TSI near 46 places Cable Lake in the mesotrophic band — moderate productivity, with seasonal swings between clearer spring water and richer late-summer conditions. Cable Lake is a shallow lake at 14 ft maximum depth, which means it warms quickly, mixes constantly, and amplifies nutrient inputs. Cable Lake covers 194 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 Polk County's 20 graded waters, Cable Lake sits at rank 2, near the top of the local distribution.

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