Kinnickinnic River Habitat Rehabilitation Project

Finished riverbank after restoration showing new stability and habitat

Cardno supported mitigation of aquatic conditions in an Area of Concern on the Kinnickinnic River in Wisconsin.

Cardno teamed with Montgomery Associates to design and implement habitat improvements to address degraded aquatic habitat conditions in the upper portion of the Milwaukee Estuary Area of Concern on the Kinnickinnic River.

This portion of the river is one of the few with natural bed and native banks remaining. It does not sustain a viable aquatic habitat due to low dissolved oxygen levels, lack of flow, and limited diversity of channel morphology.

The work improved fish passage to the upper reaches and tributaries of the Kinnickinnic River Watershed as well as the overall water quality of the Milwaukee Estuary.

Cardno designed and oversaw construction of 165 linear feet of bank stabilization and habitat structures, including tree root wads, toe wood, stone, and in-channel habitat boulders.

Our team also provided upland habitat improvements, including herbicide treatment of approximately 1,900 square feet of invasive weeds (Japanese Knotweed).
