Summary
Built in 1960, this Earth-type dam stands at 20 feet tall and stretches 325 feet in length, with a storage capacity of 100 acre-feet. Despite being regulated and inspected by the Oklahoma Water Resources Board, the dam is classified as low hazard potential with a very high risk assessment.
With a controlled spillway and one valve outlet gate, Oknoname 051040 poses a low risk of failure but is in need of a condition assessment. Although it has not been rated for its current condition, the dam is still deemed safe for use. The surrounding area covers 4 acres and has a normal storage capacity of 50 acre-feet, serving as a vital water resource in the region.
While Oknoname 051040 may not be a high-risk structure, its location in a very high-risk area raises concerns for potential emergencies. With an outdated last inspection date in 2010, there is a need for increased monitoring and assessment to ensure the dam's continued safety and effectiveness in managing water resources in Grady County, Oklahoma.

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.
