Lake Sherwood

Lake Sherwood earns a C — middle-of-the-pack water quality, with one or two parameters dragging the average down from a stronger grade. Clarity is the limiting factor — phosphorus is reasonable but suspended particles or algal cells keep water transparency below Wisconsin norms.

At a TSI of 51, Lake Sherwood reads as eutrophic — nutrient-rich enough that summer algal growth and reduced clarity are expected, not unusual. Lake Sherwood reaches 27 ft at its deepest point — typical for Wisconsin mid-sized lakes, with seasonal stratification but limited cold-water refuge. At 216 acres, Lake Sherwood fits the Wisconsin median for monitored lakes, with partial shoreline records. Within Adams County's 19 graded lakes, Lake Sherwood ranks 14 — below the local median, though not at the bottom.

Lake Sherwood is on the Wisconsin infested-waters list for zebra mussels — boaters should follow clean-drain-dry protocols when moving gear to or from the lake. Walleye are documented at Lake Sherwood, one of 4 fish species on record for the lake. A documented public access point at Lake Sherwood 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.
