Summary
Completed in 1934, this dam serves primarily for recreational purposes, offering a serene getaway at Larson Lake. With a height of 20 feet and a length of 395 feet, the dam holds a maximum storage capacity of 3,470 acre-feet and covers a surface area of 235 acres.
Managed by the North Dakota State Water Commission, Regent Dam has a spillway width of 300 feet and is classified as having a low hazard potential. The dam has undergone structural modifications in 1948 and 1986 to ensure its safety and functionality. Despite being not rated for its current condition, the dam is regularly inspected and meets state regulatory standards for operation and enforcement.
With a drainage area of 31.5 square miles and a normal storage capacity of 1,210 acre-feet, Regent Dam plays a crucial role in water resource management in the region. This moderate risk dam on the Spring Coulee stream is a vital asset for the community, offering both recreational opportunities and essential flood control measures.

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.
