Summary
Built in 1973 by the USDA NRCS, this earth dam on Hilliby Creek stands at a height of 50 feet and has a storage capacity of 1342 acre-feet, with a normal storage level of 117 acre-feet.
Despite being categorized as low hazard potential, the dam is rated as having a very high risk due to its condition assessment being marked as "Not Rated." The dam's spillway is controlled and has a width of 1 foot, with one outlet valve. The last inspection date was in 1980, and the dam is due for inspection every 5 years.
For water resource and climate enthusiasts, the SCS-Okfuskee Tributaries Site-H06 offers a unique opportunity to study the management and risks associated with flood risk reduction structures in Oklahoma. With its location in a rural area and its critical role in mitigating flood risks, this dam serves as an important case study for understanding the complexities of water resource management and the need for regular inspections and maintenance to ensure public safety and environmental protection.

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.
