Upper Springstead Lake

Upper Springstead Lake comes in at a B on the grading rubric — a respectable showing for a Wisconsin lake of its size and depth.

The lake sits in the mesotrophic zone — the band where most well-managed Wisconsin lakes fall. Upper Springstead Lake reaches 22 ft at its deepest point — typical for Wisconsin mid-sized lakes, with seasonal stratification but limited cold-water refuge. At 121 acres, Upper Springstead Lake fits the Wisconsin median for monitored lakes, with partial shoreline records. Among the 33 graded lakes in Iron County, Upper Springstead Lake sits at rank 13, above the county median.

Upper Springstead Lake has at least one documented invasive species (Curly-Leaf Pondweed), so boaters and anglers should observe clean-drain-dry steps when leaving the lake. Walleye are documented at Upper Springstead Lake, one of 6 fish species on record for the lake. 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.
