Summary
This earth dam, standing at a height of 45.5 feet, serves primarily as a Fish and Wildlife Pond with a storage capacity of 2162 acre-feet. The dam is situated along the Badger Coulee-TR river and falls under the regulatory authority of the North Dakota State Water Commission.
With a surface area of 79.8 acres and a drainage area of 17 square miles, Armourdale Dam plays a vital role in flood control and water resource management in the region. Despite being rated as having a low hazard potential, the dam's risk assessment is moderate, highlighting the importance of continued monitoring and management. The dam features an uncontrolled spillway with a width of 14 feet and a single valve outlet gate.
Although Armourdale Dam has not been rated for its condition, regular inspections are conducted by the state regulatory agency to ensure its safety and functionality. The dam's emergency action plan status and risk management measures are currently undetermined, emphasizing the need for proactive measures to address any potential risks associated with the structure. For water resource and climate enthusiasts, Armourdale Dam serves as a significant example of state-managed infrastructure aimed at enhancing environmental conservation and wildlife habitat in the area.

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.
