Jamestown, located in North Dakota along the James River, is a federally owned dam managed by the Bureau of Reclamation. Completed in 1954, this earth dam stands at 110 feet tall and serves primarily for flood risk reduction and irrigation purposes. With a storage capacity of 379,636 acre-feet and a surface area of 17,427 acres, Jamestown plays a crucial role in managing water resources in the region.

The dam has a high hazard potential and is regulated by the North Dakota State Water Commission, with regular inspections conducted by the Bureau of Reclamation. While the condition assessment is currently not available, emergency action plans have been prepared and revised periodically. The dam features an uncontrolled spillway and two slide gates for water release. Overall, Jamestown represents a significant infrastructure project that safeguards the community from flooding events and supports agricultural activities through irrigation.

The dam's location within Stutsman County, North Dakota, and its design by the Bureau of Reclamation highlight the collaboration between federal agencies and local authorities in ensuring water resource management and climate resilience. With a moderate risk assessment rating, Jamestown underscores the importance of ongoing monitoring and maintenance to mitigate potential hazards and ensure the longevity of this critical water infrastructure.
