Summary
Completed in 1965, this dam stands at a height of 17 feet and has a storage capacity of 60 acre-feet. With a controlled spillway and one valve outlet gate, this structure is primarily used for purposes other than flood control or water supply. Despite being categorized as having low hazard potential, it is subject to state regulation and inspection by the Oklahoma Water Resources Board.
The dam's risk assessment indicates a very high level of risk, possibly due to its age and condition not being rated. The last inspection took place in May 2011, with a recommended inspection frequency of every five years. As a part of the Tulsa District, the dam falls under the jurisdiction of the state regulatory agency and is situated within a distance of 8 miles from Garden Grove. With the primary purpose being classified as "Other," Oknoname 125020 serves as a significant water resource management structure in the region.
Despite its low hazard potential, the risk assessment for Oknoname 125020 raises concerns about its overall safety and condition. With a very high risk classification and a lack of recent condition assessment, it is essential for the dam owner and regulatory agencies to prioritize regular inspections and necessary maintenance to ensure the structure's integrity and functionality. As a vital component of the water management system along the TR-North Canadian River, this earth dam plays a crucial role in mitigating flood risks and providing water storage capacity for the surrounding area.

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.
