Summary
Built in 1960, this dam stands at a height of 15 feet and has a maximum storage capacity of 326 acre-feet. With a surface area of 56 acres, the dam serves as a crucial infrastructure to mitigate flood risks in the region.
Managed by the Oklahoma Water Resources Board (OWRB), this dam has a controlled spillway with a width of 2 feet and is equipped with a valve outlet gate. Despite being rated as having a low hazard potential and not being currently assessed for its condition, the dam is considered to be at a very high risk level (1). While the last inspection date dates back to 1980, the dam is still subject to regular inspections every 5 years to ensure its safety and functionality.
For water resource and climate enthusiasts, SCS-Lost Duck Creek Site-D3 presents an intriguing case study of a vital infrastructure designed to manage flood risks in the region. With its historical significance and ongoing regulatory oversight, this earth dam serves as a critical component of water resource management in Oklahoma, highlighting the importance of maintaining and assessing infrastructure to ensure public safety and environmental resilience in the face of changing climate conditions.

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.
