Summary
Built in 1960 by the USDA NRCS, this dam stands at 35 feet high and stretches 950 feet in length, with a storage capacity of 350 acre-feet. It serves as a crucial structure for managing water resources in the area, specifically on the TR-LAFLIN CREEK, with a controlled spillway and a valve outlet gate.
Despite its low hazard potential, Oknoname 051029 is considered to have a very high risk due to its age and condition, which is currently not rated. The dam is regulated by the Oklahoma Water Resources Board (OWRB) and undergoes regular inspections, with the last one conducted in August 2010. The surrounding community should be aware of the potential risks associated with this dam and be prepared for any emergencies that may arise, as there is currently no Emergency Action Plan (EAP) in place.
As an important component of the water infrastructure in the area, Oknoname 051029 highlights the need for continued monitoring and maintenance to ensure its stability and safety. With its significant storage capacity and role in water resource management, this dam serves as a vital resource for the region and underscores the importance of proactive risk management measures to safeguard against potential hazards.

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.
