Beckers Lake

Beckers Lake earns a D — measurements through 2021 show persistent nutrient pressure that limits clarity through the summer. Clarity, phosphorus, and chlorophyll-a all rate similarly, so there is no obvious single lever to pull on watershed management.

At a TSI of 65, Beckers Lake reads as eutrophic — nutrient-rich enough that summer algal growth and reduced clarity are expected, not unusual. At 53 ft of maximum depth, Beckers Lake stratifies reliably through the summer — the hypolimnion stays cooler and clearer than the surface layer suggests. The lake is compact at 35 acres, with partial shoreline records and little volume to buffer nutrient inputs. Beckers Lake ranks 2 of 2 in Calumet County — at the lower end of the locally monitored distribution.

Eurasian watermilfoil has been documented at Beckers Lake, requiring shoreline management to keep dense mats from crowding native vegetation. Walleye are documented at Beckers Lake, one of 4 fish species on record for the lake. A documented public access point at Beckers 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.
