The dam, situated on the Heart River, serves as a vital water supply source for the region, providing a storage capacity of 52.8 acre-feet and covering a surface area of 6 acres. Despite its age, the dam has undergone structural modifications in 1974 and 1986 to ensure its continued functionality.
Managed by the North Dakota State Water Commission (NDSWC), East Broadway Dam is regulated, permitted, inspected, and enforced by the state, demonstrating a commitment to safety and compliance with regulations. The dam's low hazard potential is complemented by a moderate risk assessment rating, indicating a proactive approach to risk management. The presence of an uncontrolled spillway with a width of 125 feet and a single slide gate for outlet control further enhances the dam's operational efficiency and safety measures.
The dam's historical significance, combined with its ongoing maintenance and regulatory oversight, underscores its importance in ensuring water supply reliability for the local community. As a key infrastructure asset in Stark County, East Broadway Dam serves as a testament to the collaboration between local government entities and federal agencies in safeguarding water resources and enhancing climate resilience in the region.
