Summary
The dam stands at a height of 17 feet with a hydraulic height of 15 feet and a length of 650 feet. It has a maximum storage capacity of 143 acre-feet and a normal storage level of 40 acre-feet, serving as a crucial water management structure for the area.
Managed by the Oklahoma Water Resources Board, Oknoname 121018 is regulated by the state and undergoes regular inspections, with the last one conducted in June 2011. The dam has a controlled spillway type and a low hazard potential, but a very high risk assessment rating. Despite its age, the structure remains in a not-rated condition and has not been modified in recent years. With its valve outlet gates and proximity to TR-Hominy Creek, Oknoname 121018 plays a significant role in flood control and water resource management in the region.
Enthusiasts of water resources and climate will find Oknoname 121018 an intriguing subject of study, given its historical significance, design specifications, and risk assessment status. As a vital component of the local water infrastructure, this dam serves as a focal point for understanding the interplay between human intervention and natural processes in maintaining water security and mitigating potential hazards in the area. Its location in Friendship Church, Oklahoma, further highlights the intersection of engineering, environmental stewardship, and community resilience in managing water resources for the future.

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.
