Summary
The dam, completed in 1960, stands at a height of 25 feet and spans 490 feet in length, with a storage capacity of 52 acre-feet. It serves as a crucial structure for regulating Coldwater Creek's flow, with a controlled spillway and a maximum discharge capacity of 750 cubic feet per second. Despite being categorized as having a low hazard potential, the dam is considered to have a very high risk due to its age and condition assessment not being rated.
The dam is under the jurisdiction of the Oklahoma Water Resources Board (OWRB), with state-regulated permitting, inspection, and enforcement in place. The primary purpose of Oknoname 053002 is classified as 'other', with no associated structures and a single valve outlet gate. The risk management measures and emergency response preparedness for the dam are currently not reported, raising concerns for potential safety and environmental risks. The dam's location within the Tulsa District and its association with Coldwater Creek highlight the importance of monitoring and maintaining this essential water resource infrastructure for climate and water resource enthusiasts.

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.
