Mill Creek Structure, also known as North Branch Mill Creek Dam, is a privately owned earth dam located in Yale, Michigan. Built in 1965 by the USDA-SCS, this structure serves the primary purpose of flood risk reduction along the North Branch Mill Creek. The dam stands at a height of 28 feet with a hydraulic height of 25 feet, spanning a length of 1190 feet and holding a maximum storage capacity of 2965 acre-feet.

Managed by the Natural Resources Conservation Service, Mill Creek Structure has a high hazard potential and is subject to regular inspections to ensure its satisfactory condition. The dam features an uncontrolled spillway with a width of 608 feet and is designed to handle a maximum discharge of 70800 cubic feet per second. With a drainage area of 22.9 square miles, the dam plays a crucial role in protecting the surrounding area from potential flooding events.

Despite its age, Mill Creek Structure continues to be a vital asset in the region's water resource management efforts.
