Summary
Completed in 1960, this earth dam serves multiple purposes, including flood control, irrigation, and water storage, with a maximum capacity of 116 acre-feet and a normal storage of 56 acre-feet. The dam has a controlled spillway and a single valve outlet gate.
The dam has a low hazard potential and has not been rated for condition assessment as of the last inspection in August 2006. Despite its low hazard potential, the risk assessment for Oknoname 149013 indicates a very high risk level. The dam is regulated by the Oklahoma Water Resources Board and falls under state jurisdiction for permitting, inspection, and enforcement, emphasizing the importance of proper maintenance and risk management measures to ensure the safety and integrity of the structure in the face of potential climate-related challenges.
Overall, Oknoname 149013 presents an interesting case study for water resource and climate enthusiasts, showcasing the complexities of managing a privately owned dam in a state-regulated environment. With its strategic location in Washita County, Oklahoma, and its vital role in water management, this dam serves as a reminder of the importance of proactive risk assessment and management in the face of evolving environmental conditions and potential climate impacts on water infrastructure.

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.
