Summary
Built in 1935 by the Civilian Conservation Corps and the North Dakota State Water Commission, this masonry dam serves multiple purposes, including fire protection and creating a small fish pond. With a height of 13.5 feet and a length of 140 feet, the dam provides essential storage of 294 acre-feet of water for the surrounding area.
Managed by the local government and regulated by the NDSWC, the dam has undergone multiple structural modifications over the years to ensure its continued functionality and safety. Despite being classified as having a low hazard potential, the dam poses a moderate risk due to its age and the potential for failure under extreme conditions. The risk management measures for the Lamoure City Dam are currently not specified, highlighting the importance of ongoing monitoring and maintenance to safeguard this vital water resource for the community.
With a drainage area of 2900 acres and a surface area of 115 acres, the Lamoure City Dam plays a crucial role in water management for the region. The presence of an uncontrolled spillway and a single slide gate outlet further underscore the importance of regular inspections and maintenance to mitigate any potential risks. As a focal point for both water resource enthusiasts and climate advocates, the Lamoure City Dam represents a blend of historical significance and modern-day resilience in the face of changing environmental conditions.

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.
