Summary
The dam is regulated by the Oklahoma Water Resources Board and is subject to state inspection and enforcement. It is situated along the TR-PENN CR river/stream and falls under the jurisdiction of the Tulsa District of the US Army Corps of Engineers.
With a hazard potential rated as low and a condition assessment listed as "not rated," Oknoname 113061 has a very high risk assessment ranking of 1. The dam features a controlled spillway with a width of 1 foot and a valve outlet gate. The last inspection conducted on this dam was in September 2011, with an inspection frequency of every 5 years. Despite its low hazard potential, the risk management measures and emergency action plans for this dam appear to be lacking, with no specific details provided in the data.
Overall, Oknoname 113061 presents an interesting case study for water resource and climate enthusiasts due to its unique attributes and location in Oklahoma. With a history dating back to the mid-20th century, this dam serves as a reminder of the importance of regular inspections and maintenance to ensure the safety and reliability of critical water infrastructure. Further research and analysis may be needed to fully understand the risk factors associated with this dam and to develop comprehensive risk management strategies to address any potential vulnerabilities.

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.
