Lapham Peak Pond

On the LakeGrade rubric, Lapham Peak Pond pulls an A: clarity at 16.4 ft and phosphorus readings still being added put it in the top bracket for Wisconsin. Sub-grades cluster within a single letter of each other, which usually means the lake is in stable trophic balance rather than fighting one specific stressor.

A TSI value of 37 puts Lapham Peak Pond in the oligotrophic range, where biological productivity stays low and the water column remains clear. The lake's maximum depth is not yet documented in state morphometric records — context for its physical structure remains limited. The lake is compact at 1 acres, with partial shoreline records and little volume to buffer nutrient inputs. Within Waukesha County's 48 graded lakes, Lapham Peak Pond ranks 26 — below the local median, though not at the bottom.

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