Hook Lake Wildlife Area
Hook Lake – Grass Lake Wildlife and Natural Area is a 1092 acre property located 4 miles south of Madison and McFarland in the Town of Dunn, Dane County. The property lies within Schneider Road on the north, Hawkinson Road on the east, Rutland-Dunn Townline Road on the south and Schuster road on the west. Sandhill Road runs north to south through the property between Hook Lake and Grass Lake. Hook Lake Bog ranks as one of the highest quality wetlands in Dane County and is a State Natural Area. It is a soft bog lake, which is unusual for southern Wisconsin. The lake, located in a glacial pocket, is nearly extinct with only 50-70 acres of open water remaining. The rest is covered by a floating sedge mat and emergent aquatic vegetation with tamarack swamp forest, open bog, and southern sedge meadow communities. An upland island of dry-mesic forest is also present and is rich with spring wildflowersoot. The natural area also contains restored prairie and oak savanna along the western edge of the lake. The diversity and structure of the vegetation offers a variety of habitat and cover for wildlife, including open water, reed beds, sedge, cat-tails, shrub, deciduous and coniferous forest areas. Grass Lake is a “biologically unique” wetland in Dane County and one of the few remaining deep water marshes in the county. It has a completely different character than Hook Lake, being alkaline and nutrient rich rather than acidic and nutrient poor, and supporting the typical deep marsh aquatic plants such as water lilies, pickerel weed, spike weed and duck potato. The property consists of oak and central hardwoods, as well as extensive prairie and grasslands. ManagementManagement ObjectiveThe Hook Lake and Grass Lake WA is identified as place for managing high quality wetland communities of statewide significance within the Southeast Glacial Plains Ecological Landscape according to Wisconsin’s Wildlife Action Plan [PDF 117KB].
