Summary
This earth dam stands at a height of 30 feet and has a storage capacity of 180 acre-feet, with a maximum discharge capacity of 900 cubic feet per second. The dam serves a primary purpose of "Other" and is regulated by the Oklahoma Water Resources Board, with state permitting, inspection, and enforcement in place to ensure its safety and compliance with regulations.
The dam features a controlled spillway with a width of 1 foot and is equipped with one valve for outlet gates. Despite its low hazard potential and "Not Rated" condition assessment, the risk assessment for Oknoname 113011 is classified as "Very High (1)", indicating the need for careful monitoring and risk management measures. The last inspection of the dam was conducted in August 2006, with a scheduled inspection frequency of every 5 years to ensure its continued safety and functionality.
Water resource and climate enthusiasts interested in the infrastructure and management of dams will find Oknoname 113011's data to be a valuable insight into the regulatory framework and risk assessment processes involved in maintaining such structures. With its location on the TR-Caney River and its association with the Tulsa District of the US Army Corps of Engineers, this dam serves as a critical piece of water management infrastructure in the region, highlighting the importance of responsible dam operation and maintenance in mitigating potential risks to surrounding communities and the environment.

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.
