Summary
Situated on the Briar Branch Creek, this structure serves various purposes and has a controlled spillway with a width of 2 feet. Despite its low hazard potential, the risk assessment for Oknoname 127010 indicates a very high risk level, highlighting the importance of effective risk management measures.
Owned and regulated by the Oklahoma Water Resources Board (OWRB), Oknoname 127010 has a history of state jurisdiction, permitting, inspection, and enforcement. The dam features a stone core and soil foundation, with a valve outlet gate for water control. The last inspection of this structure was conducted in October 2009, with a scheduled inspection frequency of 5 years. While the condition assessment is currently listed as "Not Rated," the risk assessment categorizes the dam as having a very high risk level, emphasizing the need for proactive risk management strategies to ensure its safety and integrity for the surrounding community and water resources.
With a surface area of 20 acres and a drainage area yet to be specified, Oknoname 127010 plays a crucial role in water storage and flood control in the region. The dam's location in Ethel, Oklahoma, under the jurisdiction of the Fort Worth District, highlights its significance in managing water resources in the area. As water resource and climate enthusiasts, understanding the design, purpose, and risk profile of dams like Oknoname 127010 is essential for promoting sustainable water management practices and ensuring the safety and resilience of critical infrastructure in the face of changing environmental conditions.

Dam Data Reference
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.
