Summary
Completed in 1966, this earth dam stands at a height of 28 feet and has a storage capacity of 1335 acre-feet. With a spillway width of 1 foot and a maximum discharge of 4170 cubic feet per second, this dam serves as a crucial infrastructure for managing water levels in the area.
Despite being categorized as having a low hazard potential, the risk assessment for SCS-Caddo Creek Site-20 indicates a very high risk level, with a DSAC (Dam Safety Action Classification) of 1. Although the dam's condition is not currently rated, it is subject to regular inspections every 5 years. Emergency preparedness measures such as an Emergency Action Plan (EAP) and inundation maps are not currently in place, highlighting the need for improved risk management strategies for this important flood control structure in the region.
With its strategic location in Ardmore and its role in flood risk reduction for the surrounding area, SCS-Caddo Creek Site-20 stands as a vital piece of infrastructure in Oklahoma's water resource management system. As climate change continues to impact weather patterns and water availability, ensuring the safety and effectiveness of dams like this one becomes increasingly important for protecting communities and ecosystems in the face of evolving environmental challenges.

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.
