Summary
Completed in 1950, this structure stands at a height of 30 feet with a hydraulic height of 24 feet and a length of 420 feet. The dam has a storage capacity of 225 acre-feet, with a normal storage level of 120 acre-feet. It is primarily used for purposes other than flood control or water supply, and is regulated by the Oklahoma Water Resources Board.
Despite being classified as having a low hazard potential, Oknoname 113063 poses a very high risk according to the data, which ranks its risk assessment as 1. The dam has one valve outlet gate and a controlled spillway, with a maximum discharge capacity of 1240 cubic feet per second. The last inspection of the dam was conducted in August 2006, with an inspection frequency of 5 years. The condition assessment of the structure is listed as "Not Rated," indicating a need for further evaluation.
While the dam's risk assessment may raise concerns among water resource and climate enthusiasts, it is essential for the responsible regulatory agency, in this case the Oklahoma Water Resources Board, to continue monitoring and managing the structure to ensure the safety of surrounding communities and the integrity of the dam. With its location on TR-Bull Creek and its proximity to Skiatook, Oknoname 113063 serves as a critical piece of infrastructure that requires ongoing attention and maintenance to mitigate potential risks and protect the environment and residents downstream.

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.
