Summary
Completed in 1991, this earth dam stands at a height of 35 feet and serves the primary purpose of flood risk reduction along the TR-Aowa Creek. With a storage capacity of 650 acre-feet and a drainage area of 3.2 square miles, this dam plays a crucial role in managing water flow in the region.
Despite its low hazard potential and satisfactory condition assessment, Aowa Creek 51-1a undergoes regular inspections every five years to ensure its structural integrity and functionality. With a maximum discharge capacity of 71 cubic feet per second, this dam serves as a vital infrastructure for flood control and water resource management in the area. The dam's location in SWS19T31R5E near Newcastle, Nebraska, highlights its strategic placement to mitigate potential flood risks and protect the surrounding communities.
Managed by the Natural Resources Conservation Service, Aowa Creek 51-1a stands as a testament to the importance of sustainable water resource management and climate resilience efforts in Nebraska. With its efficient design, solid foundation, and crucial role in flood risk reduction, this dam serves as a key infrastructure asset in safeguarding the local environment and enhancing water security in the region.

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.
