Summary
Built in 1970, this dam stands at a height of 30 feet and spans a length of 3370 feet, with a maximum storage capacity of 50 acre-feet. The dam is regulated by the Oklahoma Water Resources Board (OWRB) and is inspected, permitted, and enforced by state authorities to ensure safety and compliance.
The primary purpose of Oknoname 111068 is classified as "Other," with a low hazard potential and a very high risk assessment rating. Despite its relatively low hazard potential, the dam is closely monitored and equipped with a controlled spillway and one outlet valve. The surrounding area is at risk of inundation, making risk management measures crucial for the safety of the community.
With a river or stream named TR-COAL CREEK flowing nearby, Oknoname 111068 plays a critical role in water resource management and flood control in the region. Climate enthusiasts and water resource experts will find this dam's detailed information and risk assessment data valuable for understanding its significance in the broader ecosystem and its impact on local communities.

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.
