Watershed - Lower Manitowoc River (MA02)
Lower Manitowoc River Watershed

Details

The Lower Manitowoc River watershed includes the 168 square mile (436 square kilometers) area of land that extends from the confluence of the North and South branches of the Manitowoc River for 36 miles before entering Lake Michigan at the city of Manitowoc. More than 90 percent of the watershed is within Manitowoc County; the remaining portions lie within Brown and Calumet counties. Land use is primarily agricultural, approximately 67 percent, and about 5 percent is in urban use. The rest is woodland and wetlands, which include the Liberty Swamp and Maple Grove Swamp, both characterized by lowland hardwood species. The watershed also includes the Collins Marsh Wildlife Area, an extremely important aquatic environment.

Population, Land Use

Sewer service area plans are developed under Wisconsin Administrative Code NR 121 for cities, towns, villages etc., with populations exceeding 10,000. Plans are developed to control growth in outlying areas and to protect water quality of streams, wetlands, lakes, and groundwater. The 1990 census reported 32,521 people in city of Manitowoc and an estimated population (by municipality) of 33,761 for 1995 (WDOA 1990). The 1990 census reported 13,030 people in the city of Two Rivers and an estimated population of 13,274 for 1995 (WDOA 1990).

Nonpoint and Point Sources

There are six municipal point source dischargers and eight industrial point source dischargers in the Lower Manitowoc River Watershed: Clarks Mills Sanitary District, Manitowoc City, Reedsville Village, Rockland Sanitary District No. 1, St. Nazianz Village, Valders Village, Busch Ag. Resources Inc., Holler Lakeside Auto, Imperial Eastman, Lakeside Foods Inc. Manitowoc Plant, Manitowoc Grey Iron Foundry Inc., Manitowoc Public Utilities (two sites) and U.S. Army Corps Engineers/Manitowoc Confined Disposal Facility (CDF). The Lower Manitowoc River Watershed was one of the first five priority watersheds selected under the Wisconsin Nonpoint Source Pollution Abatement Program established in 1978. The project was assumed by the Rural Clean Water Program in 1980. The nonpoint source project was completed in 1993. Many nonpoint source problems still exist in the Lower Manitowoc River Watershed, including groundwater issues that were not addressed in old watershed projects. Since it was one of the first priority watershed projects in the state, many best management practices available to today's projects were not available to improve and protect water quality. New best management practices available today include: rotational grazing, reduced tillage, streambank easements, milkhouse waste management, cattle mounds, barnyard abandonment, and well abandonment.

Ecological Landscapes for Lower Manitowoc River Watershed

Ecological Landscapes

The Lower Manitowoc River Watershed is located primarily 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.

River and Stream QualityAll Waters in Watershed

The major concern in this part of the river has been PCB detection. The source of the PCBs has not been detected. Catfish are in the DO NOT EAT category of the consumption advisory due to PCB levels in excess of the health standard. In order to assess the impacts to human health and conduct trend monitoring, Watershed Management (WT) should sample fish in the Manitowoc River above and below the dam at Clarks Mills to determine the source and extent of the problem.

Manitowoc Public School District: Manitowoc Public School District Ais Educational Project: The Manitowoc Public School Dist proposes to develop an aquatic invasive species (AIS) education project in conjunction with the Wisconsin Maritime Museum (WMM) and Woodland Dunes Nature Center. The project elements & deliverables are specified in Manitowoc Public School District's AIS Control Grant Application, dated 7.26.06. The project includes providing AIS educational programming linked to public school sixth-grade science curriculum to all sixth grade classes in school year 2007/2008; creating permanent displays at three areas of the Rahr Memorial School Forest; creating one or more AIS informational exhibits at the WMM and developing a funding strategy to sustain the program beyond the grant period. Designs of the displays and exhibits created for this project will be submitted to DNR for approval prior to construction, & copies of the designs will be provided to DNR as part of the project's deliverables. Representatives from the Manitowoc Public School District, WMMand Woodland Dunes Nature Center will meet with a DNR project overview team at the initiation of the project to review its implementation strategy. Quarterly progress reports & a final report summarizing the project will be provided to DNR.

If consultant is to provide the final report, it is recommended that the Grantee provide the DNR AIS Coord with a draft for comment on report adequacy prior to making final payment to the consultant. DNR will be provided both paper and electronic .pdf copies of the final report along with, or prior to, submission of grantee's final payment request. If watercraft inspection is conducted as part of the project then those records will be entered into the State's online Watercraft Inspection Database. Any publications produced as part of the project will incorporate the "Stop Aquatic Hitchhikers!"\FFFD brand.

Lower Manitowoc River WatershedWatershed History Note

The Village of Valders is located within the Lower Manitowoc River watershed. Valders was settled in the 1850s by immigrants from the Valdres mountainous region of Norway, who were unable to eke out a living on their rocky hillside farms. The arrival of the railroad in 1896 allowed the community to grow, and it was incorporated into a village in 1921. As the village was founded by Norwegians, it was natural that the first churches were Lutheran: Valders Lutheran parish, Our Savior Lutheran parish, and Gjerpin Lutheran parish. These were later combined into Faith Lutheran parish (ELCA). There is also a small Protestant Conference parish. After the arrival of the railroad, many German settlers moved in who were primarily Catholic, but no parish was developed for them. To this day, there is still a significant population of Catholics, who worship at St. Gregory in St. Nazianz to the south, St. Mary of the Immaculate Conception in Clarks Mills to the north or St. Thomas the Apostle in Newton to the east. Valders is known within the state for its dolomitic limestone quarry, which produces building rock, harbor rock and gravel. Gray Woodfordian Drift soil is also described as Valderan Drift. The Valders lobe glacial advance was named after the village.
