Jupa Lake

The LakeGrade rubric puts Jupa Lake at a C: clarity at 3.0 ft, 9 µg/L of phosphorus, and a TSI of 49 signal an intermediate trophic state. Secchi readings are the weakest of the three parameters, suggesting suspended sediment or algal biomass dominates the optical signal.

Mesotrophic conditions dominate at Jupa Lake: enough nutrients for a healthy fishery, not so much that algal blooms become a chronic problem. 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 26 of 26 in Price County — at the lower end of the locally monitored 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.
