. Property along the river was acquired in parcels by the State of Wisconsin since the 1950s to provide a full range of nature based activities including hiking, wildlife viewing, hunting, fishing, and wildlife habitat. Since 1978, the beach and surrounding nature preserve have attracted picnickers and swimming day-trippers to its open and expansive shoreline. The Mazomanie Bottoms encompasses a large area of Wisconsin River floodplain forest dissected by old river channels that are dry except during periodic floods. Silver maple, elm, basswood, and ash dominate the forest; other trees include swamp white oak, cottonwood, willow, river birch, and hackberry. Openings in the canopy due to elm mortality have a dense understory of prickly ash, gray dogwood, buckthorn, and young trees. Ridges of sand support oaks, but the slough margins are nearly pure silver maple. Vining plants and lianas are found in abundance: virgin's bower, wild yam, moonseed, wild cucumber, woodbine, poison ivy, carrion flower, and grape. Sand bars and ephemeral pools along the river add considerable diversity. The forest harbors thousands of migrating birds. Nesting birds include these uncommon species: cerulean (Dendroica cerulea), Kentucky (Oporornis formosus), prothonotary (Protontaria citrea) and mourning warblers, winter wren, and brown creeper. The site has a large woodpecker population and is used in winter by bald eagles (Haliaeetus leucocephalus). Mazomanie Bottoms is owned by the DNR and was designated a State Natural Area in 1978. Seasonal changes shape the river, thereby altering the beach's size. This along with additional Wisconsin Department of Natural Resources (DNR) changing land restrictions means the actual beach area changes annually. Camping is not allowed on the sandbars near Mazomanie Bottoms. On a hot summer weekend, the beach may see hundreds of people to include families with children and recreational boaters. In the past, conservation groups have occasionally protested near the beach to ensure it remains open and free to all the citizens of Wisconsin. The clothing optional beach lies along the Lower
