Summary
Managed by the USDA NRCS, this earth dam structure stands at a height of 78 feet and has a length of 3280 feet. Completed in 1972, the reservoir has a storage capacity of 30,300 acre-feet and serves as a critical source of water for the region.
The dam on Salt Creek is regulated by the Oklahoma Water Resources Board (OWRB) and is inspected regularly to ensure its safety and functionality. With a spillway width of 4 feet and a maximum discharge rate of 3000 cubic feet per second, the dam is designed to handle controlled water release during periods of high flow. Despite being classified as having a high hazard potential, the dam is currently assessed to be in fair condition, with a risk assessment rating of very high.
In the event of an emergency, the reservoir has one valve outlet gate for water release. The last inspection of the dam took place in November 2011, and it is designated as a high-risk structure that requires vigilant management and maintenance. As a critical water supply infrastructure in the region, the SCS-Okfuskee Tributaries Site-S1 plays a crucial role in water resource management and climate resilience efforts in Oklahoma.

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.
