South Branch Pike River


Section 206, Water Resources Development Act 1996, as amended Continuing Authority Program (CAP).


Historically, the South Branch Pike River was a sluggish stream throughout most of its length with several naturally occurring plant communities including marsh, meadow, wet prairie, dry-mesic prairie, and woodland. By the late 1800s, many of these communities were converted to agricultural, residential, urban, or industrial use. Subsequently, there was a significant loss of biodiversity and adverse physical effects such as a decrease in spatial coverage of native plant communities, and a decrease in habitat suitability for various assemblages of species.

The purpose of the proposed project is ecological restoration that would provide high quality habitat for various fish and wildlife species. The need for the proposed project results from human induced disturbances within the watershed that have altered and/or modified natural biological processes and have reduced flora and fauna biodiversity.

The nonfederal sponsor, Kenosha County, requested that the Chicago District, U.S. Army Corps of Engineers (USACE) initiate a study under Section 206 of the Water Resources Development Act (WRDA) 1996, as amended, Aquatic Ecosystem Restoration authority to ascertain the feasibility of restoring important riverine habitat for fish and wildlife within the South Branch Pike River. The Integrated Feasibility Study/Environmental Assessment (IFR/EA) documents whether a project is warranted for federal participation based on a feasibility level assessment of estimated costs, potential benefits, and possible environmental impacts of various alternatives.

The 246-acre project area is located in southeast Kenosha County, Wisconsin. Due to the size and presence of major roadways, the project area was broken into two phases: Phase I and Phase II. Phase I is bordered to the south by Highway K (60th Street) and to the north by Highway 158 (52nd Street) and to the east and west by railroad tracks and is approximately 52 acres in size. Phase II is bounded to the south by Highway 158 (52nd Street) and to the north by Highway S (38th Street) and is approximately 194 acres in size.


The proposed project could offset degradation and habitat loss by providing a sustainable environmental corridor, connect isolated environmental features, improve water quality, and improve storage availability.

Nonfederal Cost:




The IFR/EA, posted here, was fully approved on March 10, 2022.  A Project Partnership Agreement with Kenosha County is slated for execution in the summer of 2022, which will allow USACE to request funding to proceed with Design and Implementation of the project.
