Hawthorne Hills South Pond

Hawthorne Hills South Pond grades an F: every scored parameter (phosphorus) rates poorly, placing it among the most stressed lakes monitored in Wisconsin.

Hypereutrophic conditions mean the lake is operating at the upper end of the productivity scale, with all the bloom risk that implies. 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. Hawthorne Hills South Pond ranks 20 of 21 in Dane County — at the lower end of the locally monitored distribution.

No invasive species are currently listed at Hawthorne Hills South Pond — the lake remains off the Wisconsin infested-waters roster. The state fisheries records do not list documented species for Hawthorne Hills South 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.
