Summary
This dam, situated on Buffalo Creek, serves a primary purpose of "Other" and has a maximum storage capacity of 50 acre-feet. With a dam height of 32 feet and a hydraulic height of 28 feet, Selman No.9 plays a crucial role in water resource management in the region.
The dam is regulated by the Oklahoma Water Resources Board (OWRB) and undergoes regular inspections, with the last inspection conducted in August 2006. Despite being rated as "Not Rated" in terms of condition assessment, the hazard potential of Selman No.9 is considered "Undetermined" with a very high risk level assigned. The dam features a controlled spillway and one valve outlet gate, ensuring proper flood control measures are in place.
Overall, Selman No.9 represents a significant infrastructure for water resource management in Oklahoma. With its strategic location on Buffalo Creek and adherence to regulatory standards, this dam contributes to the overall resilience of the region's water supply system. However, ongoing monitoring and maintenance are essential to ensure the safety and effectiveness of Selman No.9 in the face of changing climate conditions and water resource demands.

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.
