Summary

This dam, designed by USDA NRCS, stands at a height of 24.5 feet with a hydraulic height of 22.1 feet. The primary purpose of this Earth-type dam is to support fish and wildlife activities, providing a storage capacity of 35.6 acre-feet and covering a surface area of 2.3 acres. The dam is regulated by the Oklahoma Water Resources Board and is subject to state inspection and enforcement, ensuring its safety and functionality.

Situated on the Washita River, this dam is a vital resource for the surrounding environment, offering a controlled spillway and a single outlet valve for water management. Despite its low hazard potential, the risk assessment for Oknoname 30251 categorizes it as having a very high risk level. The dam has not been rated for its condition but is inspected every five years to ensure its structural integrity and compliance with regulatory standards. With a congressman representative of Frank D. Lucas (R) and a state jurisdiction in place, this dam plays a crucial role in supporting the local ecosystem and water resources in Oklahoma.

Overall, Oknoname 30251 stands as a testament to the importance of water resource management and climate resilience. As a privately owned structure with public benefits, this fish and wildlife pond serves as a key component of the local ecosystem, offering storage, flood control, and recreational opportunities. With its design by USDA NRCS and state regulation by the Oklahoma Water Resources Board, this dam exemplifies the collaboration between government agencies and private owners in safeguarding water resources and promoting environmental sustainability in the region.

Dam Data Reference

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.
