Summary
Built in 1966 by USDA NRCS, this Earth-type dam stands at a height of 23 feet and serves primarily for flood risk reduction purposes. With a maximum storage capacity of 489 acre-feet and a normal storage of 49 acre-feet, this dam covers a surface area of 17 acres and has a controlled spillway width of 1 foot.
Despite being rated as having a low hazard potential and not yet assessed for condition, SCS-Caddo Creek Site-22 poses a very high risk, as per the risk assessment. The dam features a single valve outlet gate and has undergone inspection every five years, with the last recorded inspection dating back to January 1, 1980. While emergency action and inundation maps preparation status remain unknown, the dam's risk management measures and DSAC assignment are also not specified in the available data.
Water resource and climate enthusiasts interested in the engineering and management aspects of dams, particularly those designed for flood risk reduction, may find the details of SCS-Caddo Creek Site-22 intriguing. Being a state-regulated structure in Oklahoma, this dam's characteristics, such as its dimensions, storage capacity, and risk assessment, provide valuable insights into the vital role it plays in water resource management and disaster mitigation efforts in the region.

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.
