Plattsmouth 10-A dam
Plattsmouth 10-A
Plattsmouth 10-A is a vital flood risk reduction structure located in Cass, Nebraska along the TR-Missouri River. Built in 1959 by the USDA NRCS, this earth-type dam stands at 40 feet in height and spans 946 feet in length. With a storage capacity of 137 acre-feet, it serves to protect the surrounding area from potential flooding events, with a high hazard potential but a satisfactory condition assessment as of August 2020.
Managed by the local government, specifically the Nebraska Department of Natural Resources, Plattsmouth 10-A is subject to state regulations, permitting, inspections, and enforcement to ensure its proper functioning and safety. Situated within the Kansas City District, this dam plays a crucial role in mitigating flood risks and safeguarding the community of Plattsmouth. As a key component of flood control infrastructure, it highlights the importance of proactive measures in water resource management and climate resilience efforts.
With a primary purpose of flood risk reduction, Plattsmouth 10-A symbolizes the collaborative efforts between federal agencies, local governments, and designers like the USDA NRCS in safeguarding communities and ecosystems against the impacts of extreme weather events. As climate change continues to pose challenges to water resources, the significance of structures like Plattsmouth 10-A in managing flood risks and enhancing resilience becomes increasingly apparent. Its role in protecting lives, property, and critical infrastructure underscores the importance of sustainable water management practices in the face of a changing climate.

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 Plattsmouth 10-A
Where does the data for Plattsmouth 10-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 High 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.
