Summary
The dam, primarily designed for irrigation purposes, stands at a height of 19.9 feet and spans 300 feet in length. It holds a storage capacity of 415.8 acre-feet and is situated on the West Branch of Long Lake Creek, within the St. Paul District of the US Army Corps of Engineers.
Managed by the North Dakota State Water Commission, Braddock Dam is classified as a low hazard potential structure with a moderate risk assessment rating. The dam features an uncontrolled spillway with a width of 175 feet, and is regulated, permitted, inspected, and enforced by the state agency. Despite having a condition assessment of "Not Rated," the dam's risk management measures are under evaluation, highlighting the importance of continuous monitoring and maintenance to ensure the safety and functionality of the structure.
With its historical significance and vital role in providing irrigation water, Braddock Dam serves as a key infrastructure in the region. The dam's presence not only supports agricultural activities but also contributes to the overall water resource management in the area. As water resource and climate enthusiasts, understanding the design, operation, and maintenance of structures like Braddock Dam is essential for sustainable water utilization and environmental conservation efforts in North Dakota.

Dam Data Reference
Condition Assessment
SatisfactoryNo existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
Fair
No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
Poor A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency. Investigations and studies are necessary.
Unsatisfactory
A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
Not Rated
The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
Significant
Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environment damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
Low
Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
Undetermined
Dams for which a downstream hazard potential has not been designated or is not provided.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
