Summary
Built in 1965, this Earth-type dam stands at a height of 30 feet and spans 500 feet in length, with a storage capacity of 360 acre-feet. The dam is regulated by the Oklahoma Water Resources Board and is equipped with a controlled spillway and a single valve outlet gate. Despite its low hazard potential, the dam is classified as having a very high risk due to its condition assessment not being rated.
The Selman Robert dam plays a crucial role in water resource management in the region, providing irrigation and flood control for the surrounding area. With a maximum discharge capacity of 1630 cubic feet per second, the dam serves as a vital infrastructure for maintaining water levels in times of heavy rainfall or drought. The dam's location in a rural area highlights the importance of proper inspection and maintenance to ensure its continued functionality and safety.
Although the Selman Robert dam has not been inspected since 2011 and is currently rated as "Not Rated" in terms of condition assessment, it is imperative that regular inspections and risk management measures are put in place to mitigate the potential risks associated with its aging infrastructure. With a dedicated emergency action plan and adherence to regulatory guidelines, the dam can continue to serve as a reliable water resource for the community while minimizing the risk of any potential hazards.

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.
