Summary
This dam stands at a height of 20 feet and spans 300 feet in length, with a primary purpose classified as 'Other'. The dam is situated on TR-Sleeping Bear Creek and has a storage capacity of 110 acre-feet, with a spillway type classified as 'Controlled'.
Despite being rated as having a low hazard potential, Oknoname 059022 is considered to have a very high risk level. The dam has not been assessed for its condition, and the last inspection was conducted in August 2011. The dam features a single valve outlet gate, and there are no associated structures or locks present. The regulatory oversight for this dam falls under the jurisdiction of the Oklahoma Water Resources Board, with state permitting, inspection, and enforcement in place.
For water resource and climate enthusiasts, Oknoname 059022 presents an intriguing case study of a privately owned earth dam in Oklahoma. With its unique design features and regulatory framework, this dam offers a glimpse into the complexities of managing water resources in a state with a diverse hydrological landscape. Despite its low hazard potential, the high risk assessment underscores the importance of regular inspections and maintenance to ensure the safety and integrity of the structure.

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.
