The LakeGrade rubric puts St. Croix 8 Mi. Upstream of Point Douglas Dr Lake at a C: clarity at 8.9 ft, 51 µg/L of phosphorus, and a TSI of 53 signal an intermediate trophic state. 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.

Eutrophic conditions are the baseline here: clarity drops noticeably in late summer, and dissolved oxygen near the bottom can become a concern. St. Croix 8 Mi. Upstream of Point Douglas Dr Lake is unusually deep for Wisconsin at 60 ft, which buffers the lake against summer warming and helps the deep water stay oxygenated. St. Croix 8 Mi.
