Pike River Restoration
The Pike River Watershed has been an ongoing interest of local jurisdictions for many years.
In the Comprehensive Plan for the Pike River Watershed (1983), the Southeastern Wisconsin Regional Planning Commission (SEWRPC) noted the reach of the Pike River between Petrifying Springs Park and Kenosha Country Club was impounded. That water movement negatively affected local fish populations. This plan was the first to outline specific management techniques for the watershed.
Restoration of the Pike River within Petrifying Springs Park addresses a “critical area” of the river as highlighted in the EPA-approved Nine Element Pike River Watershed Plan (2013). This site is extremely important as it is one of the largest and least fragmented green infrastructure hubs in the watershed. Streambank and channel restoration efforts follow the plan’s recommended practices.
Kenosha County’s restoration activities on the Pike River are part of a large, ongoing effort conducted within the Pike River Watershed. The Village of Mount Pleasant restored a seven-mile corridor of the North Branch of the Pike River. Kenosha County has taken a proactive approach to restoring the Main Branch of the Pike River that flows through Petrifying Springs Park and the UW-Parkside campus.
The Pike River Restoration Projects within Petrifying Springs Park were partially funded with support from numerous stakeholders. This includes the U.S. Environmental Protection Agency EPA/Great Lakes Restoration Initiative, the Fund for Lake Michigan, Wisconsin DNR River Protection Program, and revenue from the Petrifying Springs Biergarten and Boundless Adventures outdoor adventure park in Bristol.
Phase I: Completed in 2018
In 2017, Kenosha County secured a Great Lakes Restoration Initiative Grant from the U.S. Environmental Protection Agency (EPA) to initiate Phase I restoration efforts. Kenosha County addressed streambank erosion and improved in-stream structure and streamflow dynamics on a 3,145-linear-foot reach of the stream. Native vegetation plantings were installed within the 5.2-acre habitat to stabilize and improve filtration and infiltration of the riparian corridor.
A wetland delineation was completed in the summer of 2017. Engineering, design, and construction documents were completed in the spring of 2018. The restoration work at Petrifying Springs Park began in July 2018. All grading work was completed by November 2018.

Phase II: Completed in 2021
Phase II encompassed a 3,280-linear-foot stretch of the Pike River. It included planting native vegetation on 4.83 acres of riverbank habitat within the central section of Petrifying Springs Park.
Similar to Phase I, stone revetments were installed to prevent erosion and stabilize the once-eroded, steep slopes along the river. Natural elements, such as toe wood protection, log vanes, and planting of native vegetation, were also installed within the river. This protects the stream bank from eroding and provides in-stream cover for fish.
Approximately three-quarters of a mile of new trails were developed. This allows the public to gain recreational access to the Pike River corridor, including for fishing and the use of non-motorized watercraft. The playground in the park’s Area No. 4, which has been subjected to flooding, will be relocated in 2022 to a spot west of the river, outside of the floodplain.
