Mccoll Pond

Mccoll Pond sits at a C on the grading scale — not impaired, not pristine, with summer measurements that vary year to year. The three sub-grades — clarity, phosphorus, and chlorophyll-a — track close together, so no single parameter is dragging the average.

A TSI near 47 places Mccoll Pond in the mesotrophic band — moderate productivity, with seasonal swings between clearer spring water and richer late-summer conditions. Mccoll Pond is a shallow lake at 11 ft maximum depth, which means it warms quickly, mixes constantly, and amplifies nutrient inputs. The lake is compact at 23 acres, with 1.0 miles of shoreline and little volume to buffer nutrient inputs. Among the 17 graded lakes in Scott County, Mccoll Pond sits at rank 7, above the county median.

Eurasian watermilfoil is established at Mccoll Pond, which can dampen recreational access and pressure the native plant community. The fishery is bass-led, with 7 documented species across the lake's records. 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.
