Dowling Lake

The LakeGrade rubric puts Dowling Lake at a C: clarity readings still being added, 55 µg/L of phosphorus, and a TSI of 62 signal an intermediate trophic state.

Eutrophic conditions are the baseline here: clarity drops noticeably in late summer, and dissolved oxygen near the bottom can become a concern. 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. Within Douglas County's 40 graded lakes, Dowling Lake ranks 23 — below the local median, though not at the bottom.

Dowling Lake has at least one documented invasive species (Curly-Leaf Pondweed), so boaters and anglers should observe clean-drain-dry steps when leaving the lake. The fishery includes walleye among the lake's 5 documented species — a notable draw for Wisconsin anglers. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
