Summary
Completed in 2003, this earth dam stands at a height of 78 feet and spans 312 feet in length, serving primarily for flood risk reduction along the TR-Missouri River. With a maximum storage capacity of 29 acre-feet and a normal storage of 19 acre-feet, the dam covers a surface area of 2 acres within its jurisdiction.
Managed by the Omaha District of the US Army Corps of Engineers, Ponca S Park Dam has a low hazard potential and is deemed to be in satisfactory condition as of the last inspection in April 2020. The dam's emergency action plan status and risk assessment details are currently undocumented, but it is subject to regular inspections every five years to ensure its structural integrity and safety measures. Despite its modest size and capacity, the dam plays a crucial role in mitigating flood risks and protecting the surrounding area from potential water-related disasters.
For water resource and climate enthusiasts, Ponca S Park Dam offers a glimpse into the intricate network of infrastructure designed to manage water flow and safeguard communities against natural disasters. Its presence along the TR-Missouri River highlights the collaborative efforts between state and federal agencies in ensuring the resilience and sustainability of water resource management systems. As climate change continues to pose challenges to water management, structures like Ponca S Park Dam stand as vital assets in safeguarding our environment and communities against the impacts of extreme weather events.

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.
