The dam, standing at a height of 10 feet with a hydraulic height of 9 feet, impounds Big Sucker Creek to create O'Neal Lake with a normal storage capacity of 500 acre-feet. The dam has a surface area of 138 acres and drains an 8.1 square mile watershed, serving as a picturesque site for outdoor enthusiasts to enjoy.
Despite its low hazard potential, the dam's condition was assessed as unsatisfactory during its last inspection in October 2011. With an inspection frequency of every 5 years, the dam poses a moderate risk level that necessitates ongoing risk management measures to ensure its safety and integrity. The spillway, with a width of 15 feet, is uncontrolled, adding to the complexity of managing water levels during periods of high discharge. As a key feature in the Detroit District, O'Neal Lake Dam remains an important structure for both water resource management and recreation in the region.
