Reisner Lake

On the LakeGrade scale Reisner Lake grades a B, with clarity at 6.5 ft and 18 µg/L of phosphorus placing it above the Wisconsin median. Secchi readings are the weakest of the scored parameters, suggesting suspended sediment or algal biomass dominates the optical signal.

Mesotrophic conditions dominate at Reisner Lake: enough nutrients for a healthy fishery, not so much that algal blooms become a chronic problem. At only 5 ft deep, Reisner Lake is shallow — wind keeps the water column mixed and sediment resuspension drives phosphorus levels harder to manage. The lake is compact at 96 acres, with partial shoreline records and little volume to buffer nutrient inputs. Within Florence County's 39 graded lakes, Reisner Lake ranks 28 — below the local median, though not at the bottom.

An invasive species record — Purple Loosestrife — has been logged at Reisner Lake; Wisconsin DNR maintains the official infested-waters list. The fishery is bass-led, with 3 documented species across the lake's records. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
