Summary
Built in 1999, this earth dam stands at a height of 16.45 feet and has a maximum storage capacity of 86 acre-feet. With a low hazard potential and moderate risk assessment, the dam is under the jurisdiction of the North Dakota State Water Commission (NDSWC) and is regulated, permitted, inspected, and enforced by the state.
This dam plays a vital role in minimizing the impact of flooding in the region, safeguarding the surrounding areas from potential water-related disasters. Despite not being rated for its condition assessment, County Rd15 Detention Dam has not required any modifications since its completion. With an uncontrolled spillway and no outlet gates, the dam serves its primary purpose effectively, ensuring the safety of the local community and infrastructure during times of heightened water levels.
For water resource and climate enthusiasts, County Rd15 Detention Dam stands as a testament to effective flood risk reduction measures in place in North Dakota. With its strategic location and design, the dam serves as a critical infrastructure project that contributes to the overall water management efforts in the area. As the state continues to prioritize water resource management and resilience to climate change, structures like County Rd15 Detention Dam play a crucial role in ensuring the safety and security of the community against the impacts of extreme weather events.

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.
