Summary
This dam, situated on TR BUFFALO CR, serves a primary purpose other than flood control or water supply, with a maximum storage capacity of 110 acre-feet. Despite being rated as having a low hazard potential, it is designated as a very high risk due to its location and structural characteristics.
Managed by the Oklahoma Water Resources Board, Oknoname 059062 undergoes regular state inspections, permitting, and enforcement to ensure its safety and compliance with regulations. The dam's spillway is controlled with a width of 1 foot, and it has a single valve outlet gate. While the condition assessment is not rated, the dam is monitored for any necessary risk management measures to mitigate potential hazards associated with its very high risk designation.
With an emergency action plan status unknown and no recent updates on inundation maps or risk assessment summaries, Oknoname 059062 remains a critical structure in the region with a need for continued monitoring and maintenance to uphold its safety and integrity. As an essential component of the water resource infrastructure in Buffalo, Oklahoma, this dam plays a vital role in water management and climate resilience efforts in the area, making it a significant site for water resource and climate enthusiasts to study and monitor.

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.
