Canton Dam, also known as Canton Lake, is a gravity dam located on the North Canadian River in Oklahoma. Completed in 1948 by the US Army Corps of Engineers, its primary purpose is flood risk reduction, with additional benefits for irrigation and water supply. The dam stands at 68 feet tall, with a structural height of 68 feet and a length of 15,140 feet. It has a storage capacity of 383,800 acre-feet and a maximum discharge of 339,200 cubic feet per second.

Despite being classified as having a high hazard potential, Canton Dam's risk assessment is very low according to a 2017 evaluation by USACE. Various risk management measures have been implemented, including the construction of an auxiliary spillway, anchoring of the primary spillway, and widening of the earthen dam. The dam is continuously monitored and inspected to ensure its integrity, with regular updates to the Emergency Action Plan and coordination with local and state emergency responders for evacuation planning. In the event of a dam failure, the areas most at risk include Oklahoma City, as well as several towns along the river. Overall, Canton Dam serves as a crucial structure for flood protection in the region, supported by diligent risk management efforts and ongoing maintenance practices.
