Summary
Completed in 1986, this stone-core dam stands at a height of 29.7 feet and serves primarily for flood risk reduction. With a storage capacity of 89 acre-feet and a normal storage level of 15 acre-feet, this dam plays a crucial role in managing water resources in the area.
Despite its low hazard potential, Oknoname 30203 is classified as having a very high risk due to its location and purpose. The dam has not been rated for its condition assessment, and information on its emergency action plan and risk management measures is not available. While the dam has not been modified in recent years and does not have locks or associated structures, it is subject to regular inspections with a frequency of every 5 years to ensure its structural integrity and functionality.
For water resource and climate enthusiasts, Oknoname 30203 provides a fascinating case study of a privately owned dam in Oklahoma that contributes to flood risk reduction. Its design by USDA NRCS and regulation by OWRB showcase the collaboration between different agencies to manage water resources effectively. Understanding the risk assessment and management strategies associated with this dam can offer valuable insights into the challenges and opportunities in maintaining critical infrastructure for water management in the region.

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.
