Summary
Built in 2002, this earth dam stands at a height of 32 feet with a length of 727 feet, providing a storage capacity of 170 acre-feet. It is regulated and inspected by the Nebraska Department of Natural Resources, ensuring its structural integrity and compliance with state regulations.
The dam's hazard potential is classified as low, with a satisfactory condition assessment as of March 2017. While the dam has not been modified in recent years, regular inspections every five years help to assess its ongoing maintenance needs and emergency preparedness. Its primary purpose of flood risk reduction underscores its importance in protecting local communities and infrastructure from potential flooding events.
Overall, Holdredge Street Dam plays a vital role in water resource management in Nebraska, with a focus on mitigating flood risks and ensuring public safety. Its strategic location and design elements, such as a stone core and soil foundation, contribute to its effectiveness in managing water levels and protecting downstream areas. As climate change continues to impact weather patterns, the importance of well-maintained dams like Holdredge Street Dam becomes increasingly crucial in safeguarding communities and ecosystems from the threats of flooding.

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.
