Summary
Situated on the South Fork Maple River, this earth dam stands at a height of 11.5 feet and has a storage capacity of 75 acre-feet. While its current condition is not rated, the dam is regulated by the North Dakota State Water Commission (NDSWC) and undergoes regular state inspection, permitting, and enforcement.
Despite its undetermined hazard potential, Maple River Dam plays a crucial role in water resource management for the region. With a surface area of 24.8 acres and a drainage area of 10 square miles, the dam provides flood control and water storage benefits to the surrounding community. Although details about spillway type and maximum discharge are not specified, the dam's presence helps mitigate potential risks associated with extreme weather events and climate variability.
As a significant infrastructure within the St. Paul District of the US Army Corps of Engineers, Maple River Dam contributes to the overall resilience of the local water system. While more information is needed regarding emergency preparedness measures and risk assessment, the dam's historical significance and ongoing regulatory oversight highlight its importance in safeguarding water resources and enhancing climate resilience in Dickey County.

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.
