Summary
This earth dam was completed in 1968 and stands at a height of 15 feet, with a hydraulic height of 11 feet and a structural height of 12 feet. The dam's primary purpose is listed as "Other", with a low hazard potential and a very high risk assessment rating. It is regulated by the Oklahoma Water Resources Board (OWRB) and is subject to state permitting, inspection, and enforcement.
The dam has a storage capacity of 50 acre-feet, with a maximum discharge rate of 4557 cubic feet per second. It is equipped with a controlled spillway and a single valve outlet gate. The dam is situated on TR COAL CREEK and is within the jurisdiction of the Tulsa District of the US Army Corps of Engineers. Despite not being rated for condition assessment, the dam has an inspection frequency of 5 years and has not had a recorded inspection since June 2011.
Despite its relatively low hazard potential, the very high risk assessment of Oknoname 121002 indicates potential dangers associated with the dam. With its location in a high-risk area, proper risk management measures should be in place to ensure the safety and integrity of the structure. Enthusiasts of water resources and climate may find interest in the unique characteristics and regulatory aspects of this dam, as well as the potential implications for local water management and safety.

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.
