Horlick Dam


Great Lakes Fishery & Ecosystem Restoration (Section 506, WRDA 2000), as amended.


The study area is the immediate vicinity of the Horlick’s Dam on the Root River in Racine, Wisconsin. The Root River drainage area upstream of the dam is approximately 198 square miles, encompassing portions of Waukesha, Milwaukee, Kenosha and Racine counties. The Horlick’s Dam specifically resides on the Root River at river mile 5.3, or 5.3 miles upstream of Lake Michigan.

Horlick’s Dam blocks fish passage to 160.2 miles of upstream river and tributary habitat, and 6,176 acres of wetland habitat.

The goal for this project is to restore riverine connectivity to the Root River watershed, and to restore riverine habitat within the reach affected by Horlick’s Dam. Objectives are to reestablish quality and connectivity of riverine and riparian habitats.

The project was determined to be in the federal Interest in July 2020. In partnership with Racine County Public Works and Development Services, completion of the Feasibility Study Report would complete the plan formulation process, identify cost effective plans for ecosystem restoration purposes, and complete preliminary design of the recommended plan. The report will serve as the decision document for the approval of construction funding.
