Jupa Lake

The LakeGrade rubric puts Jupa Lake at a C: clarity at 1.5 ft, 9 µg/L of phosphorus, and a TSI of 54 signal an intermediate trophic state. Secchi readings are the weakest of the three parameters, suggesting suspended sediment or algal biomass dominates the optical signal.

Eutrophic conditions are the baseline here: clarity drops noticeably in late summer, and dissolved oxygen near the bottom can become a concern. Jupa Lake is a shallow lake at 13 ft maximum depth, which means it warms quickly, mixes constantly, and amplifies nutrient inputs. Jupa Lake is small — 9 acres alongside partial shoreline records — which makes it sensitive to even modest changes in watershed runoff or recreational pressure. Jupa Lake ranks 10 of 27 in Price County — solidly in the upper half of the local distribution.

No invasive species are currently listed at Jupa Lake — the lake remains off the Wisconsin infested-waters roster. The fishery is bass-led, with 2 documented species across the lake's records. A documented public access point at Jupa Lake makes the lake usable for shore fishing, paddle craft, and trailered boats. 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.
