Glisezinski Lake
Portage County, WisconsinMesotrophic
On the LakeGrade scale Glisezinski Lake grades a B, with clarity at 9.0 ft and 16 µg/L of phosphorus placing it above the Wisconsin median. The lake's weakest score is on Secchi depth — the water looks more turbid than its phosphorus number alone would predict.
The lake sits in the mesotrophic zone — the band where most well-managed Wisconsin lakes fall. At only 11 ft deep, Glisezinski Lake is shallow — wind keeps the water column mixed and sediment resuspension drives phosphorus levels harder to manage. The lake is compact at 35 acres, with partial shoreline records and little volume to buffer nutrient inputs. Among the 28 graded lakes in Portage County, Glisezinski Lake sits at rank 12, above the county median.
No invasive species are currently listed at Glisezinski Lake — the lake remains off the Wisconsin infested-waters roster. The fishery is bass-led, with 3 documented species across the lake's records. A documented public access point at Glisezinski Lake makes the lake usable for shore fishing, paddle craft, and trailered boats. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
