Summary
This earth dam stands at a height of 26 feet and has a hydraulic height of 24.2 feet, providing a storage capacity of 112 acre-feet. With a surface area of 1.16 acres and a drainage area of 0.24 square miles, Hartington Dam plays a crucial role in managing water resources in the region.
Managed by the local government and regulated by the Nebraska Department of Natural Resources, Hartington Dam is inspected regularly to ensure its structural integrity and safety. The dam has a satisfactory condition assessment and a high hazard potential, emphasizing the importance of its role in protecting the surrounding area from potential flooding events. The dam's emergency action plan and risk management measures are in place to mitigate any potential risks and ensure the safety of the community.
Adrian Smith (R) represents the area in Congress, highlighting the political significance of Hartington Dam in the region. With its completion in 2015, the dam has become a key component in the water resource management system, providing flood risk reduction and enhancing water security for the residents of Hartington and beyond. As a vital piece of infrastructure, Hartington Dam showcases the intersection of engineering, climate resilience, and environmental stewardship in safeguarding communities against water-related challenges.

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.
