Summary
Constructed in 1972 by the USDA NRCS, this earth dam stands at a height of 45 feet and has a storage capacity of 152 acre-feet. The primary purpose of this dam is flood risk reduction, serving as a vital tool in managing water flow in the area.
Managed by the Nebraska Department of Natural Resources, Aowa Creek 1-2 is regulated, inspected, and enforced to ensure its structural integrity and safety. With a low hazard potential and fair condition assessment, this dam plays a significant role in protecting the surrounding community from potential flooding events. The dam's location in the Omaha District, along with its association with the Natural Resources Conservation Service, underscores its importance in water resource management and climate resilience efforts.
With a drainage area of 0.7 square miles and a maximum discharge capacity of 633 cubic feet per second, Aowa Creek 1-2 is a vital component of the local water infrastructure. Its presence not only reduces flood risk but also contributes to the overall water resource management in the region. As climate change continues to impact water availability and extreme weather events, structures like Aowa Creek 1-2 play a crucial role in safeguarding communities and ecosystems against the challenges of a changing climate.

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.
