Summary
This flood risk reduction structure on Massey Creek stands at a height of 48 feet and has a length of 1300 feet, providing storage capacity of 1275 acre-feet. With a controlled spillway and a valve outlet gate, the dam has a low hazard potential and a very high risk assessment rating.
Although the last inspection of SCS-Wildhorse Creek Site-009 was conducted in 1980, the dam remains in a not rated condition as per the data available. Despite its age, the dam serves a critical purpose in flood risk reduction for the region. With the state regulatory agency OWRB overseeing permitting, inspection, and enforcement, the structure plays a vital role in water resource management in Oklahoma. The presence of USACE in the data signifies the potential for collaboration and support from federal agencies in maintaining and upgrading the dam.
For water resource and climate enthusiasts, SCS-Wildhorse Creek Site-009 offers a fascinating case study of a historic earth dam that continues to play a significant role in managing flood risk in the region. The structure's design by USDA NRCS and its state-regulated status highlight the importance of collaboration between federal and state agencies in ensuring the safety and effectiveness of water infrastructure. With its unique characteristics and risk profile, this site presents an opportunity for further research and analysis in the realm of water resource management and climate resilience.

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.
