Summary
Built in 1997 by the USDA NRCS, this earth dam stands at a height of 37 feet and has a length of 1120 feet. With a storage capacity of 298 acre-feet and a drainage area of 10 square miles, this dam plays a crucial role in managing water resources in the area.
Owned by the local government and regulated by the NE DNR, Aowa Creek 12-17 is in fair condition with a low hazard potential. The dam has undergone inspections every 5 years, with the last assessment conducted in April 2016. Its emergency action plan status and risk management measures are currently unavailable, highlighting the need for continued monitoring and maintenance to ensure its effectiveness in flood risk reduction and water resource management.
Situated on Silver Creek in Ponca, Nebraska, Aowa Creek 12-17 serves as a vital infrastructure for the community. With its stone core and soil foundation, the dam plays a crucial role in protecting the area from potential flooding events. As water resource and climate enthusiasts, it is essential to recognize the importance of maintaining and investing in such structures to ensure the resilience of our water infrastructure in the face of changing environmental conditions.

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.
