Summary
Completed in 1963, this dam stands at a height of 18 feet and has a length of 450 feet, with a storage capacity of 120 acre-feet. Despite its low hazard potential, the dam is regulated, inspected, and enforced by the Oklahoma Water Resources Board to ensure its structural integrity and safety for the surrounding community.
The dam features a controlled spillway and a single valve outlet gate for water management. Although it has not been rated for its condition assessment, the risk assessment for Oknoname 01101 is classified as very high, indicating the importance of regular inspections and maintenance. The dam's emergency action plan status, inundation maps, and risk management measures have not been updated or prepared, highlighting the potential need for further safety protocols in case of a flood event.
With Congressman Frank D. Lucas representing the area in which Oknoname 01101 is located, the dam remains a critical infrastructure for flood protection in Blaine County, Oklahoma. Despite its age, the dam continues to serve its purpose in mitigating flood risks and protecting the local community along the TR-Salt Creek watershed.

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.
