Summary
Completed in 1970, this structure stands at 20 feet in height with a hydraulic height of 15 feet and a length of 660 feet. The dam has a storage capacity of 73 acre-feet and a normal storage level of 54 acre-feet, serving as a crucial water resource for the area. The primary purpose of this dam is categorized as "Other", with a spillway type of "Controlled" and a hazard potential rated as "Low".
Situated on the TR-South Fork Calvalry Creek, Oknoname 149038 is regulated by the Oklahoma Water Resources Board and undergoes regular inspections, with the last one conducted in August 2006. Although the condition assessment is listed as "Not Rated", the risk assessment for this dam is categorized as "Very High (1)", highlighting the importance of proper risk management measures. Despite its federal agency ownership status being listed as 0, this dam plays a crucial role in water resource management in the region, emphasizing the need for continued monitoring and maintenance to ensure its safety and functionality for the community it serves.

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.
