Summary
Constructed in 1976 by USDA NRCS, this dam serves the primary purpose of flood risk reduction along the TR-SPRING CREEK. With a height of 28 feet and a storage capacity of 102 acre-feet, this structure plays a crucial role in managing water resources in the region.
Managed by the Oklahoma Water Resources Board (OWRB), Oknoname 149015 has a controlled spillway and a low hazard potential. Despite being not rated for its condition assessment, the dam is inspected every 5 years to ensure its structural integrity and functionality. The risk assessment for this dam is classified as very high, emphasizing the importance of proper risk management measures to mitigate potential hazards and protect the surrounding communities.
As an essential infrastructure for flood control in the area, Oknoname 149015 underscores the significance of sustainable water resource management and climate resilience. With its strategic location and design features, this dam serves as a vital asset in safeguarding against flooding events and ensuring the safety and well-being of the local population.

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.
