Mesotrophic conditions dominate at Fawn Lake-Deep Hole: enough nutrients for a healthy fishery, not so much that algal blooms become a chronic problem. Fawn Lake-Deep Hole is a shallow lake at 14 ft maximum depth, which means it warms quickly, mixes constantly, and amplifies nutrient inputs. At 29 acres, Fawn Lake-Deep Hole sits below the Wisconsin median: a small water where shoreline activity has an outsized effect on water quality. Fawn Lake-Deep Hole sits at rank 31 of 57 in Burnett County, in the lower half of the local distribution.

No invasive species are currently listed at Fawn Lake-Deep Hole — the lake remains off the Wisconsin infested-waters roster. Bass fishing is part of the appeal: the species list runs to 3, anchored by largemouth and/or smallmouth bass. 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.
