Scs-Waterfall-Gilford Creek Site-05 Reservoir Report
Last Updated: December 5, 2025
SCS-Waterfall-Gilford Creek Site-05 in McCurtain, Oklahoma is a privately owned Earth dam constructed in 1975 by the USDA NRCS for the primary purpose of flood risk reduction along the TR-Waterfall Creek.

Summary
This impressive structure stands at a height of 26 feet with a length of 975 feet, providing a maximum storage capacity of 552 acre-feet and a normal storage of 64 acre-feet. The dam features a controlled spillway with a width of 1 foot and an outlet gate valve for water release.
Despite being classified as having a low hazard potential, the risk assessment for SCS-Waterfall-Gilford Creek Site-05 indicates a very high risk level, which should be a cause for concern for water resource and climate enthusiasts. The dam has not been rated for condition assessment, with the last inspection conducted in 1980. Emergency action plans, inundation maps, and risk management measures for the site are either absent or not up to date, highlighting the need for improved safety protocols and monitoring.
Overall, SCS-Waterfall-Gilford Creek Site-05 serves as a vital flood control infrastructure in the Fort Worth District, yet its outdated inspection records and high risk assessment warrant further attention and action from regulatory agencies like OWRB. With its location in a flood-prone area and the potential implications of a dam failure, it is essential to prioritize the safety and maintenance of this critical water resource structure to ensure the protection of surrounding communities and the environment.

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.
