The Marsh Creek Watershed drains 44 square miles and is surrounded by agricultural fields. It has a medium susceptibility for groundwater contamination based on WDNR groundwater susceptibility mapping. Marsh Creek watershed was selected as an Environmental Quality Improvement Program (EQIP) project. This program, funded by the U.S. Natural Resources Conservation Service (NRCS), targets critical watersheds for implementation of agricultural best management practices that will also protect water resources. This watershed does not contain any municipalities within its boundaries, nor any named lakes.
The Southeast Glacial Plains Ecological Landscape makes up the bulk of the non-coastal land area in southeast Wisconsin. This Ecological Landscape is made up of glacial till plains and moraines. Most of this Ecological Landscape is composed of glacial materials deposited during the Wisconsin Ice Age, but the southwest portion consists of older, pre-Wisconsin till with a more dissected topography. Soils are lime-rich tills overlain in most areas by a silt-loam loess cap. Agricultural and residential interests throughout the landscape have significantly altered the historical vegetation. Most of the rare natural communities that remain are associated with large moraines or in areas where the Niagara Escarpment occurs close to the surface.
Historically, vegetation in the Southeast Glacial Plains consisted of a mix of prairie, oak forests and savanna, and maple-basswood forests. Wet-mesic prairies, southern sedge meadows, emergent marshes, and calcareous fens were found in lower portions of the Landscape. End moraines and drumlins supported savannas and forests. Agricultural and urban land use practices have drastically changed the land cover of the Southeast Glacial Plains since Euro-American settlement. The current vegetation is primarily agricultural cropland. Remaining forests occupy only about 10% of the land area and consist of maple-basswood, lowland hardwoods, and oak. No large mesic forests exist today except on the Kettle Interlobate Moraine which has topography too rugged for agriculture. Some existing forest patches that were formerly savannas have succeeded to hardwood forest due to fire suppression.
Monitoring & Projects
Projects including grants, restoration work and studies shown below have occurred in this watershed. Click the links below to read through the text. While these are not an exhaustive list of activities, they provide insight into the management activities happening in this watershed.
Citizen Stream Monitoring
Collect chemical, physical, and/or biological water quality data to assess the current overall stream health. The data can inform management decisions and may be used to identify impaired waters for biennial lists.
