Summary
Completed in 1950, this dam on the TR-Rush Creek serves purposes beyond flood control, with a primary purpose categorized as 'Other'. The dam has a storage capacity of 100 acre-feet and a spillway width of 1 foot, ensuring controlled discharge in times of excess water flow.
Managed by the Oklahoma Water Resources Board, Oknoname 051050 has a state-regulated status with provisions for permitting, inspection, and enforcement. Despite its low hazard potential, the dam is considered to have a very high risk due to its condition assessment being 'not rated'. The last inspection in 2002 highlighted the need for a more frequent inspection schedule, with an interval of 5 years currently in place to monitor the structural integrity of the dam.
The dam's location in Grady County, Oklahoma, under the jurisdiction of the Tulsa District, makes it a critical water resource for the region. With a congressman representative of Tom Cole (R), the dam's infrastructure is essential for the protection of the surrounding areas from potential flooding. As climate enthusiasts and water resource advocates, it is important to monitor the risk assessment and management measures for Oknoname 051050 to ensure the safety and sustainability of this vital infrastructure in the face of changing climate patterns.

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.
