Summary
Constructed in 1960, this earth-type dam stands at a height of 18.7 feet and has a storage capacity of 134.5 acre-feet, serving the crucial purpose of protecting the surrounding area from potential flooding events. Despite its low hazard potential, the dam's current condition is assessed as poor, indicating a need for maintenance and potential upgrades to ensure its long-term effectiveness.
Managed by the Nebraska Department of Natural Resources, Hardenbrook Dam is subject to state regulations, inspections, and enforcement to guarantee its safety and functionality. Although the dam's condition assessment may raise concerns, its strategic location and design contribute to mitigating flood risks in the region. With a drainage area of 7.26 square miles and a normal storage capacity of 85.8 acre-feet, the dam plays a vital role in safeguarding the local community and ecosystem from the adverse impacts of extreme weather events.
As a key component of flood risk management in the area, Hardenbrook Dam serves as a critical infrastructure for water resource and climate enthusiasts. Its historical significance, functional purpose, and structural characteristics make it an essential asset in the ongoing efforts to enhance resilience against natural disasters and promote sustainable water management practices in Nebraska.

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.
