Summary
Built in 2001 by the USDA NRCS, this structure serves primarily for irrigation purposes with a maximum storage capacity of 138.34 acre-feet. The dam stands at a height of 28 feet and has a controlled spillway type with a width of 1 foot.
Despite being classified as having a low hazard potential, Oknoname 30143 is considered to have a very high risk due to its location and design. The dam has not been rated for its condition assessment, and the last inspection was conducted in September 2010. The dam is regulated by the Oklahoma Water Resources Board (OWRB) and meets state permitting, inspection, and enforcement requirements.
For water resource and climate enthusiasts, Oknoname 30143 presents an interesting case study in dam infrastructure management. With its unique design features and location on Dead Women Creek, this dam serves as a critical irrigation source in Caddo County. The risk associated with this structure highlights the importance of regular inspections and maintenance to ensure its long-term safety and functionality in the face of changing climate conditions.

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.
