Summary
Completed in 1940, this earthen dam on TR-Salt Creek serves a primary purpose of "Other" and has a capacity of 70 acre-feet of water storage. With a low hazard potential and not currently rated for condition assessment, this dam has a controlled spillway and one outlet gate for water release.
Managed by the Oklahoma Water Resources Board, Oknoname 111031 is under state jurisdiction and regulation, with permitting, inspection, and enforcement processes in place. The dam has a very high risk assessment rating of 1, indicating the potential for significant consequences in the event of failure. While the dam has not been modified in recent years and lacks Emergency Action Plan (EAP) preparation, there is a need for ongoing risk management measures to mitigate the identified risks associated with this structure.
In the event of an emergency, the contact information and guidelines for response are not currently updated or prepared. Despite the absence of recent assessments and preparedness measures, Oknoname 111031 remains a critical infrastructure for water resource management in the area, calling for proactive measures to ensure the safety and integrity of the dam and surrounding communities in the face of potential climate and water-related challenges.

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.
