Aowa Creek 12-8 dam
Aowa Creek 12-8
Aowa Creek 12-8, located in Dixon, Nebraska, is a vital water resource managed by the local government with oversight from the Nebraska Department of Natural Resources. This earth dam, designed by the USDA NRCS in 1972, serves multiple purposes including flood risk reduction. With a structural height of 44 feet and a storage capacity of 236 acre-feet, the dam plays a crucial role in managing water flow and protecting the surrounding area from potential flooding events.
The dam's fair condition assessment and low hazard potential indicate a reliable infrastructure that is regularly inspected to ensure its structural integrity. Its location on TR-Silver Creek in the Omaha District further emphasizes its importance in the region's water management system. With a drainage area of 0.9 square miles and a maximum discharge capacity of 4765 cubic feet per second, Aowa Creek 12-8 is equipped to handle significant water flow, providing a level of protection to the local community.
In the event of an emergency, the dam is well-prepared with established inspection and enforcement protocols in place. While the dam's risk assessment and management measures are not explicitly outlined, its operational history and design features suggest a proactive approach to water resource management and climate resilience. Aowa Creek 12-8 stands as a testament to the importance of sustainable infrastructure in safeguarding against natural disasters and ensuring the continued availability of water resources for the community.

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.
- 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.
- 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.
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, environmental 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.

About Aowa Creek 12-8
Where does the data for Aowa Creek 12-8 come from?
Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.
How often is the report updated?
NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.
What does the Low hazard rating mean?
The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.
What's "% of normal"?
The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).
Can I get alerts when storage crosses a threshold?
Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.
