Summary
Built in 1970, this earth dam stands at a height of 15 feet with a hydraulic height of 11 feet and a length of 321 feet. With a storage capacity of 50 acre-feet, it serves a primary purpose that falls under the category of "Other." The dam is regulated by the Oklahoma Water Resources Board (OWRB) and has a low hazard potential, but is classified as having a very high risk due to its structural condition.
Despite being relatively small in size, Oknoname 137067 plays a crucial role in water resource management in the area. It has a controlled spillway with a width of 1 foot and an outlet gate with a single valve. The dam is regularly inspected with a frequency of every 5 years, with the last inspection conducted in September 2011. While the condition assessment is marked as "Not Rated," the risk assessment indicates a high level of risk associated with the dam, warranting close monitoring and potential management measures to ensure safety and mitigate any potential hazards.
For water resource and climate enthusiasts, Oknoname 137067 presents an intriguing case study in dam infrastructure and risk management. Its location in Stephens County, Oklahoma, within the jurisdiction of the Fort Worth District of the US Army Corps of Engineers, highlights the importance of maintaining and monitoring small dams to ensure the safety and security of surrounding communities. As climate change continues to impact water resources, understanding the condition and risks associated with dams like Oknoname 137067 is essential for sustainable water management practices and disaster preparedness.

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.
