Summary
Built in 2001 by the USFWS, this earth dam stands at a height of 11.6 feet and has a storage capacity of 100.3 acre-feet. Its primary purpose is for fire protection, stock, or small fish pond, serving as a vital resource in the region.
Managed by the NDSWC, Hintz Dam is regulated by the state of North Dakota and undergoes regular inspections to ensure its safety and integrity. With a low hazard potential and a moderate risk assessment rating, the dam plays a crucial role in water resource management in the area. Despite not being rated for condition assessment, Hintz Dam remains a key structure for environmental conservation and climate resilience.
Located in the St. Paul District, Hintz Dam serves as a vital component in the local ecosystem, providing essential water storage capacity and flood control measures. With its uncontrolled spillway and stone core, the dam is equipped to handle potential emergencies and protect the surrounding community. As a significant contributor to water conservation efforts in North Dakota, Hintz Dam stands as a testament to the importance of sustainable water resource management in the face of a changing climate.

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.
