Summary

Built in 1965, this earth dam stands at a height of 22 feet and serves a primary purpose that is classified as 'Other'. The dam has a storage capacity of 99 acre-feet and a normal storage level of 79 acre-feet, with a maximum discharge rate of 2278 cubic feet per second.

Although the hazard potential is rated as 'Low', the risk assessment for Oknoname 149025 is considered 'Very High (1)'. Despite being regulated by the Oklahoma Water Resources Board and boasting state-permitting, inspection, and enforcement protocols, the dam's condition assessment is marked as 'Not Rated', indicating a lack of recent evaluation. The structure features a controlled spillway type and is equipped with one valve outlet gate, with a last inspection date recorded in 2003.

Water resource and climate enthusiasts interested in the infrastructural aspects of dams in Oklahoma may find Oknoname 149025 to be an intriguing subject of study. With its unique design and risk assessment profile, this privately owned dam on Boggy Creek stands as a noteworthy example of water management in the Washita County region. The combination of low hazard potential and high risk assessment adds complexity to the understanding of this vital water resource infrastructure.

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.
