Scs-Waterfall-Gilford Creek Site-07 Reservoir Report
Last Updated: December 6, 2025
SCS-Waterfall-Gilford Creek Site-07 is a state-regulated earth dam located in McCurtain, Oklahoma, designed by the USDA NRCS in 1965 for flood risk reduction along TR-Waterfall Creek.

Summary
Standing at 24 feet in height and 800 feet in length, this dam provides a maximum storage capacity of 114 acre-feet with a normal storage level of 56 acre-feet over a surface area of 5 acres. With a controlled spillway and one outlet valve, the dam has a low hazard potential and is not currently rated for condition assessment.
Despite its age, SCS-Waterfall-Gilford Creek Site-07 remains a crucial piece of infrastructure for managing flood risk in the area. With a very high risk assessment rating of 1, it is essential for the state regulatory agency, OWRB, to ensure that proper inspections and enforcement measures are in place to maintain the dam's integrity and safety. Although the last inspection date was in 1980, the dam still meets state permitting requirements and is subject to regular inspections every 5 years.
As water resource and climate enthusiasts, it is important to recognize the significance of structures like SCS-Waterfall-Gilford Creek Site-07 in protecting communities from the impacts of extreme weather events. By understanding the design, purpose, and state-regulated status of this dam, we can appreciate the efforts made by agencies like the USDA NRCS and OWRB to safeguard against flooding and ensure the resilience of water resources in Oklahoma.

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.
