Summary

Completed in 1965, this dam on TR-CRINER CREEK stands at a height of 26 feet and has a length of 900 feet, providing a storage capacity of 154 acre-feet. With a controlled spillway and valve outlet gates, the dam has a low hazard potential and is categorized as having a very high risk level.

Managed by the Oklahoma Water Resources Board, this dam is regulated, permitted, inspected, and enforced by the state agency. Despite not having a federal agency owner or funding, Oknoname 087041 is well maintained and meets all necessary guidelines and requirements. The surrounding area is at risk of inundation, making it crucial for emergency preparedness and risk management measures to be in place for this important water resource structure.

For water resource and climate enthusiasts, Oknoname 087041 serves as a significant landmark in Oklahoma's water infrastructure. Its design and construction highlight the importance of proper dam maintenance and emergency planning in the face of potential risks and high inundation levels. As a vital component of the state's water management system, this dam plays a crucial role in ensuring the safety and security of the surrounding community and environment.

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.
