Scs-Roaring Creek Site-008 Reservoir Report
Last Updated: December 6, 2025
SCS-Roaring Creek Site-008, located in Grady, Oklahoma, is a state-regulated earth dam designed by the USDA NRCS in 1966 for flood risk reduction along the TR-Roaring Creek.

Summary
With a dam height of 33 feet and a length of 1000 feet, this structure provides a maximum storage capacity of 687 acre-feet and a normal storage of 115 acre-feet over a surface area of 23 acres. The controlled spillway, with a width of 1 foot, can handle a maximum discharge of 1634 cubic feet per second.
Despite being classified as having a low hazard potential, the dam's risk assessment is marked as very high due to its high-risk profile, with a DSAC assigned risk rating of 1. While the condition assessment is currently not rated and the last inspection dates back to 1980, the dam is subject to state permitting, inspection, and enforcement by the Oklahoma Water Resources Board. With its valve outlet gate and proximity to the Tulsa District, SCS-Roaring Creek Site-008 stands as a significant structure for water resource and climate enthusiasts in the region.

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.
