Wilson Creek 7-A dam
Wilson Creek 7-A
Wilson Creek 7-A is a vital flood risk reduction structure located in the heart of Otoe, Nebraska. Constructed in 1973 by the USDA NRCS, this earth dam stands at a height of 38 feet and boasts a normal storage capacity of 421 acre-feet, serving a drainage area of 6.1 square miles. With a structural height of 41 feet and a length of 1280 feet, this dam plays a crucial role in protecting the surrounding area from potential flooding events.
Managed by the local government and regulated by the Nebraska Department of Natural Resources, Wilson Creek 7-A has been deemed to have a low hazard potential and is currently in satisfactory condition as of the last inspection in November 2018. While no spillway type or width is specified, the dam's maximum discharge capacity is recorded at 5901 cubic feet per second, ensuring effective water flow management during peak flow periods. With its strategic location and significant impact on flood control in the region, Wilson Creek 7-A stands as a testament to the importance of sustainable water resource management in the face of changing climate patterns.
As climate change continues to pose challenges to water resource management, structures like Wilson Creek 7-A play a crucial role in mitigating the impacts of extreme weather events in Nebraska. With its earth dam design and stone core foundation, this dam represents a key asset in the state's flood risk reduction strategy. The dedication to regular inspections, maintenance, and enforcement by the Nebraska DNR ensures that Wilson Creek 7-A remains a reliable and effective barrier against potential flooding threats, providing essential protection to the local community and ecosystem.

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 Wilson Creek 7-A
Where does the data for Wilson Creek 7-A 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.
