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.
A TSI in the eutrophic range signals a lake doing what nutrient-loaded waters do — supporting an active algal community at the cost of clear water. 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 21 graded lakes in Dane County, Whalen Road Pond sits at rank 8, above the county median.
No invasive species are currently listed at Whalen Road Pond — the lake remains off the Wisconsin infested-waters roster. 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. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
