Summary
With a surface area of 7 acres and a length of 390 feet, this structure serves various purposes and is regulated by the Oklahoma Water Resources Board (OWRB).
Despite its low hazard potential, Oknoname 051021 has been classified as having a very high risk (1) due to potential climate-related challenges. While the dam has not been rated for its condition assessment, it undergoes inspections every 5 years, with the last inspection conducted in August 2010. The dam features a controlled spillway, one valve outlet gate, and is constructed primarily of stone and soil materials. Additionally, its location in Grady County, Oklahoma, falls under the jurisdiction of the Tulsa District of the US Army Corps of Engineers.
Overall, Oknoname 051021 serves as a crucial water resource infrastructure in the region, providing both storage and flood control benefits. As climate change continues to impact water resources, the proper maintenance and monitoring of dams like Oknoname 051021 are essential to ensure their resilience and effectiveness in mitigating potential risks and hazards associated with extreme weather events.

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.
