Summary

Built in 1981 by the USDA NRCS, this dam stands at a height of 45 feet and has a hydraulic height of 43 feet, with a structural height of 48 feet. With a normal storage capacity of 67 acre-feet and a maximum storage of 162 acre-feet, this dam plays a vital role in managing water resources in the region.

Owned and regulated by the local government and the Nebraska Department of Natural Resources, Aowa Creek 22-3 is inspected regularly to ensure its satisfactory condition and functionality. With a drainage area of 0.9 square miles and a maximum discharge capacity of 296 cubic feet per second, this dam is equipped to handle significant water flow and reduce the risk of flooding in the surrounding areas. Its location along TR-Aowa Creek makes it a critical infrastructure for flood control and water management in the region.

Overall, Aowa Creek 22-3 serves as a key component in the water resource and climate management efforts in Dixon, Nebraska. With its strategic design and purposeful construction, this dam plays a crucial role in protecting the local community from potential hazards and ensuring the efficient management of water resources in the area.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
