Summary
Built in 1976 by the USDA NRCS, this flood risk reduction structure stands at 30 feet tall and spans 1550 feet in length, with a storage capacity of 1020 acre-feet. Despite its low hazard potential, the dam has a very high risk assessment rating, indicating the need for diligent monitoring and management.
Managed by the Oklahoma Water Resources Board (OWRB), the SCS-Okfuskee Tributaries Site-N01 features a controlled spillway and a single valve outlet gate. While the dam's condition has not been rated, it undergoes inspections every five years, with the last assessment conducted in 1980. The surrounding area is at risk of inundation, but no specific risk management measures or emergency action plans have been reported for this site.
With its historical significance as a flood control structure and its critical role in managing water resources in the region, the SCS-Okfuskee Tributaries Site-N01 serves as a vital piece of infrastructure in safeguarding communities from potential flooding events. As water resource and climate enthusiasts, understanding the design, purpose, and risk profile of this dam can offer valuable insights into the intersection of human-made structures and natural environments in the face of changing climate conditions.

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.
