Summary
Completed in 1988, this dam serves multiple purposes including flood risk reduction and other water resource management activities. With a height of 49 feet and a hydraulic height of 48 feet, it has a storage capacity of 216 acre-feet and covers a drainage area of 0.7 square miles.
Despite its low hazard potential and satisfactory condition assessment, Aowa Creek 41-3 is subject to state regulation, inspection, and enforcement. Situated on the TR-Aowa Creek, this dam plays a crucial role in managing water flow and protecting the surrounding area from potential flooding events. The last inspection in May 2017 deemed the structure in good condition, with a regular inspection frequency of every 5 years.
Owned by the local government, Aowa Creek 41-3 stands as a testament to effective water resource management in Nebraska. With its stone core and soil foundation, this dam continues to fulfill its purpose of mitigating flood risks and ensuring the safety of the community. As a key infrastructure maintained by the Natural Resources Conservation Service, Aowa Creek 41-3 remains a vital component of the region's water resource and climate resilience efforts.

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.
