Summary

Built in 1960, it stands at a height of 25 feet and has a storage capacity of 100 acre-feet. The dam, primarily made of earth and stone, serves as a structure for the TR-Buckeye Creek, with a controlled spillway and a single outlet valve.

Despite being classified as having a low hazard potential, Oknoname 107005 is considered to have a very high risk level, with a risk assessment rating of 1. The dam has not been officially rated for its current condition, and the last inspection took place in May 2011. The dam is regulated by the Oklahoma Water Resources Board and undergoes regular inspections, with a designated inspection frequency of 5 years.

With its unique design and historical significance, Oknoname 107005 offers a fascinating opportunity for water resource and climate enthusiasts to study the impact of dams on local ecosystems and water management practices in Oklahoma. The dam's location along TR-Buckeye Creek provides a valuable case study for understanding the role of earth dams in water conservation and flood control efforts within the state. Its risk assessment highlights the importance of ongoing monitoring and maintenance to ensure the safety and functionality of critical water infrastructure in the region.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
