Whalen Road Pond

Dane County, WisconsinLimited DataEutrophic

On the scoring rubric Whalen Road Pond grades a D: clarity readings still being added and 66 µg/L of phosphorus keep it in the lower bracket for Dane County. Clarity, phosphorus, and chlorophyll-a all rate similarly, so there is no obvious single lever to pull on watershed management.

At a TSI of 65, Whalen Road Pond reads as eutrophic — nutrient-rich enough that summer algal growth and reduced clarity are expected, not unusual. The lake's maximum depth is not yet documented in state morphometric records — context for its physical structure remains limited. The lake's surface area is not consistently recorded across state datasets — physical context remains partial. Among the 23 graded lakes in Dane County, Whalen Road Pond sits at rank 10, above the county median.

Whalen Road Pond has no invasive species recorded in Wisconsin state databases as of 2021, though prevention practices still apply at all access points. The state fisheries records do not list documented species for Whalen Road 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.
