Summary
Built in 1966 by the USDA NRCS, this earth dam stands at a height of 36 feet with a length of 1800 feet, serving the primary purpose of flood risk reduction along the Elm River. With a storage capacity of 6040 acre-feet, the dam plays a crucial role in protecting the surrounding area from potential flooding events.
Managed by the NDSWC and regulated by the state of North Dakota, Elm River Deten.Dam#2 has a significant hazard potential and a moderate risk assessment rating. The spillway, with a width of 450 feet, is uncontrolled, ensuring the efficient release of excess water during periods of high flow. While the dam's condition assessment is currently listed as "Not Rated," regular state inspections and enforcement measures are in place to ensure its safety and functionality.
Despite its age, Elm River Deten.Dam#2 continues to provide essential flood risk reduction services to the community, with a normal storage capacity of 468 acre-feet. With its strategic location and design, this dam stands as a testament to effective water resource management and climate resilience efforts in North Dakota, safeguarding the region against potential water-related disasters.

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.
