Summary
Completed in 1950, this dam stands at a height of 35 feet and has a hydraulic height of 30 feet. It serves multiple purposes, with a primary purpose listed as "Other" and is regulated by the Oklahoma Water Resources Board, with state permitting, inspection, and enforcement in place.
The dam has a storage capacity of 160 acre-feet and covers a surface area of 3 acres. It has a controlled spillway with a width of 1 foot and is equipped with a valve outlet gate. The hazard potential of this dam is rated as low, with a very high risk assessment score of 1. Although the condition of the dam is currently not rated, it has a regular inspection frequency of 5 years, with the last inspection conducted in November 2001.
Overall, Oknoname 113141 is a significant water resource structure in Oklahoma, providing storage and flood control benefits along TR-LONG TREE CR. With its state-regulated status and low hazard potential, this dam plays a crucial role in water management and protection efforts in the region. Its design and construction reflect the engineering expertise involved in its development, ensuring its functionality and safety for years to come.

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.
