Summary

Standing at a height of 25 feet with a length of 1170 feet, this structure serves multiple purposes with a storage capacity of 340 acre-feet. It has a controlled spillway and a valve outlet gate, ensuring low hazard potential and a very high risk assessment rating. The dam is regulated, inspected, and enforced by the Oklahoma Water Resources Board, demonstrating compliance with state regulatory standards.

Despite its low hazard potential, Oknoname 095003 poses a significant risk due to its high-risk assessment rating. While it has not been condition-rated, it has a regular inspection frequency of 5 years, with the last inspection conducted in December 2010. The dam meets state permitting and enforcement requirements and is located in a region represented by Congressman Markwayne Mullin. With its stone core and soil foundation, this dam plays a crucial role in managing water resources in Marshall County, Oklahoma, contributing to flood control and water supply for the surrounding area.

Overall, Oknoname 095003 is a vital infrastructure in the Fort Worth District, providing essential water management functions in the region. With its controlled spillway and valve outlet gate, the dam ensures safe operation and low hazard potential. Despite its very high risk assessment rating, the structure remains in compliance with state regulations and is regularly inspected to ensure public safety and water resource management in Marshall County.

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.
