Kiowa Crossing Dam, also known as Kiowa Crossing Reservoir, is a private dam located in Winnebago, Illinois, near the city of Roscoe. Built in 1980 by Sargent Engineering Co., this earth dam stands at 18 feet tall and stretches 830 feet in length. Its primary purpose is for recreation, offering a storage capacity of 143 acre-feet and a maximum discharge of 1363 cubic feet per second.

Managed by the Illinois Department of Natural Resources, Kiowa Crossing Dam is regulated, inspected, and enforced by state authorities to ensure its safety and compliance with regulations. Despite its significant hazard potential, the dam is deemed to have a moderate risk level. While the condition assessment is currently not available, the Emergency Action Plan (EAP) was last revised in 2015, and the dam is inspected every 3 years to mitigate any potential risks.

Situated on the Tributary of North Branch Kinnikinnick Creek, Kiowa Crossing Dam offers recreational opportunities for water resource and climate enthusiasts in the area. With its uncontrolled spillway and outlet gates, the dam provides a picturesque setting for outdoor activities while maintaining a balance between conservation and public safety.
