Summary
This dam stands at a height of 23 feet with a length of 900 feet, providing a storage capacity of 170 acre-feet. Despite its low hazard potential and not being rated for condition assessment, the dam has a very high risk rating of 1 due to its location and potential impact in the event of a breach.
Managed by the Natural Resources Conservation Service, this site is state-regulated by the Oklahoma Water Resources Board with permitting, inspection, and enforcement in place. The spillway is controlled with a width of 1 foot, and the dam features a valve outlet gate. Although last inspected in 1980, the dam has an inspection frequency of 5 years, reflecting a commitment to maintaining its safety and integrity. With a very high risk assessment, it is crucial for stakeholders to ensure that proper risk management measures are in place to mitigate any potential threats to the surrounding community and environment.
For water resource and climate enthusiasts, SCS-Waterfall-Gilford Creek Site-03 serves as a significant structure in flood risk reduction efforts along TR-Waterfall Creek in Oklahoma. With a strategic location and considerable storage capacity, this Earth dam underscores the importance of proactive monitoring and maintenance to address its very high risk rating. As a vital component of the state's water infrastructure, continued attention to this site is imperative to safeguard against potential hazards and ensure the safety of downstream communities and ecosystems.

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.
