The Branch River Watershed is located in the northwest corner of Manitowoc County and the southern part of Brown County. The watershed is 69,443 acres in size and includes 186 miles of streams and rivers, 166 acres of lakes and 8943 acres of wetlands. The watershed is dominated by agriculture (78%) and wetlands (13%) and is ranked high for nonpoint source issues affecting streams and groundwater.
The Branch River Watershed lies within The Central Lake Michigan Coastal Ecological Landscape which stretches from southern Door County west across Green Bay to the Wolf River drainage, then southward in a narrowing strip along the Lake Michigan shore to central Milwaukee County. Owing to the influence of Lake Michigan in the eastern part of this landscape, summers there are cooler, winters warmer, and precipitation levels greater than at locations farther inland. Dolomites and shales underlie the glacial deposits that blanket virtually all of the Central Lake Michigan Coastal Ecological Landscape. The dolomite Niagara Escarpment is the major bedrock feature, running across the entire landscape from northeast to southwest. Series of dolomite cliffs provide critical habitat for rare terrestrial snails, bats, and specialized plants. The primary glacial landforms are ground moraine, outwash, and lakeplain. The topography is generally rolling where the surface is underlain by ground moraine, variable over areas of outwash, and nearly level where lacustrine deposits are present. Important soils include clays, loams, sands, and gravels. Certain landforms, such as sand spits, clay bluffs, beach and dune complexes, and ridge and swale systems, are associated only with the shorelines of Lake Michigan and Green Bay.
Historically, most of this landscape was vegetated with mesic hardwood forest composed primarily of sugar maple, basswood, and beech. Hemlock and white pine were locally important, but hemlock was generally restricted to cool moist sites near Lake Michigan. Areas of poorly drained glacial lakeplain supported wet forests of tamarack, white cedar, black ash, red maple, and elm, while the Wolf and Embarrass Rivers flowed through extensive floodplain forests of silver maple, green ash, and swamp white oak. Emergent marshes and wet meadows were common in and adjacent to lower Green Bay, while Lake Michigan shoreline areas featured beaches, dunes, interdunal wetlands, marshes, and highly diverse ridge and swale vegetation. Small patches of prairie and oak savanna were present in the southwestern portion of this landscape.
Bellevue Urban Storm Water Plan Update
This project is an installation of nonpoint source best management practices to contribute to the restoration of Wisconsin�s waters and was funded by the 319 grant. Storm water planning activities will be undertaken by the municipality and will result in the following products: updated storm water management plan for the developed urban area and updated storm water management plan for new development.
