Summary

Completed in 1950, this Earth-type dam stands at a height of 50 feet with a hydraulic height of 40 feet and a structural height of 50 feet. It serves a primary purpose of "Other" and has a storage capacity of 1500 acre-feet, with a normal storage level of 150 acre-feet. The dam, situated on Ranch Creek, has a spillway type of "Controlled" with a width of 1 foot.

Despite being categorized as having a "Low" hazard potential, Oknoname 113096 is associated with a very high risk assessment rating of 1. It has not been rated for its condition assessment, but its last inspection was conducted in September 2011 with a frequency of once every 5 years. The dam has one valve outlet gate and covers a surface area of 25 acres. The risk management measures and other related factors for this dam are currently unspecified.

Overall, Oknoname 113096 is a significant structure in the water resource management of Osage, Oklahoma, with a rich history dating back to the mid-20th century. Its presence on Ranch Creek contributes to the local ecosystem and water supply, while also posing a high risk that necessitates careful monitoring and management. Water resource and climate enthusiasts would find this dam to be an intriguing subject of study and discussion within the realm of water infrastructure and environmental sustainability.

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.
