Salmo Pond

Salmo Pond earns an A — water clarity, phosphorus, and chlorophyll-a all rate among the best monitored waters in Dane County. 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.

The lake's low TSI puts it in oligotrophic territory — the cleanest of the four trophic classes, but also the most vulnerable to nutrient-driven shifts. 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 3 acres, with partial shoreline records and little volume to buffer nutrient inputs. Within Dane County's 23 graded waters, Salmo Pond sits at rank 2, near the top of the local distribution.

Salmo Pond carries an invasive watermilfoil record — boat-launch decontamination and shoreline care matter more here than at uninfested lakes. The fishery is bass-led, with 3 documented species across the lake's records. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
