Summary
Completed in 1940, this earth dam stands at a height of 30 feet and spans a length of 3250 feet, with a primary purpose categorized as "Other." The dam's reservoir has a storage capacity of 90 acre-feet, with a normal storage level of 45 acre-feet and a surface area of 1 acre. The dam is regulated by the Oklahoma Water Resources Board (OWRB) and is subject to state jurisdiction, permitting, inspection, and enforcement.
Situated on the TR-COAL CREEK river or stream in the Tulsa District of Oklahoma, Oknoname 111050 has a controlled spillway design with a width of 1 foot. The dam's hazard potential is rated as low, with a very high risk assessment score of 1. While the condition of the dam is currently not rated, it undergoes inspections every 5 years, with the last inspection conducted in August 2011. Emergency action plans and inundation maps for the dam are yet to be prepared, and the risk management measures for the dam are unspecified.
Even though Oknoname 111050 is not owned or funded by federal agencies, it plays a crucial role in water resource management in the region. With its unique design and historical significance, this dam serves as a key element in the infrastructure of the area, contributing to flood control, water storage, and overall environmental conservation efforts. For water resource and climate enthusiasts, Oknoname 111050 presents a fascinating case study in the management and regulation of dams in the state of Oklahoma, showcasing the complex interplay between human infrastructure and natural ecosystems in the face of changing climate patterns.

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.
