Summary
The dam, designed by the USDA NRCS, was completed in 1958 for the primary purpose of flood risk reduction. With a height of 35 feet and a hydraulic height of 30 feet, the dam has a storage capacity of 1029 acre-feet and a spillway width of 1 foot.
Despite being in fair condition, the dam has a high hazard potential and a very high risk assessment rating. It is equipped with one valve outlet gate and has a controlled spillway. The dam has been inspected periodically, with the last inspection conducted in September 2011. The dam is under the jurisdiction of the OWRB and is subject to state permitting, inspection, and enforcement.
Overall, the SCS-Saddle Mountain Creek Site-005 serves as a crucial infrastructure for managing flood risks in the area. Its strategic location along TR-Saddle Mountain Creek and its design characteristics demonstrate its importance in protecting the surrounding communities and ecosystems from potential flood events. Enthusiasts of water resources and climate management would find this site to be an intriguing case study in dam engineering and flood risk mitigation efforts in Oklahoma.

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.
