Completed in 1966, this earthen dam stands at a height of 33 feet and spans a length of 583 feet, creating a reservoir with a maximum storage capacity of 2570 acre-feet. The dam's spillway type is uncontrolled, with a width of 17 feet, and it poses a high hazard potential with a poor condition assessment as of September 2019.
Despite its risk assessment of moderate, the Cornwall Creek Dam has not had any modifications or emergency action plan updates since 2019. The inspection frequency is set at every three years, with the last inspection conducted in September 2019. The dam's location within the Cheboygan County in Michigan poses a potential threat to the surrounding area in the event of a failure, highlighting the importance of ongoing monitoring and maintenance efforts to ensure the safety and integrity of this crucial water resource structure for both recreational and environmental purposes.
