Summary
With a height of 28 feet and a length of 800 feet, this dam provides a storage capacity of 273 acre-feet and serves as a controlled spillway structure. Despite its age, the dam has a low hazard potential and has not been rated for its condition assessment.
Managed by the Oklahoma Water Resources Board, the SCS-Waterfall-Gilford Creek Site-08 is subject to state regulatory oversight, including permitting, inspection, and enforcement. With a maximum discharge capacity of 1391 cubic feet per second, the dam's primary purpose is flood risk reduction, offering vital protection to the surrounding area. Although the last inspection was conducted in 1980, the dam's risk assessment remains very high, reflecting the importance of continued monitoring and maintenance to ensure its integrity and safety.
As a key infrastructure for flood control in the region, the SCS-Waterfall-Gilford Creek Site-08 underscores the critical role of water resource management in mitigating climate-related risks. With a designated emergency action plan yet to be prepared and updated, there is a need for increased attention to risk management measures and guidelines to safeguard against potential hazards and ensure the long-term resilience of this essential water resource structure.

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.
