Summary
Completed in 1966, this earth dam stands at 29 feet tall and spans 700 feet in length, with a storage capacity of 124 acre-feet. Situated on TR-DRY CREEK in the city of ALEX, this structure is owned by the state and falls under the jurisdiction of the Oklahoma Water Resources Board (OWRB).
Despite being classified as having a low hazard potential, the dam at SCS-Roaring Creek Site-D3 poses a very high risk according to the data available. The spillway type is controlled, with a width of 1 foot, and the dam features a valve outlet gate for water release. While the last inspection date was in 1980, the dam is subject to a regular inspection frequency of 5 years to ensure its safety and structural integrity. The condition assessment is currently listed as "not rated".
With its strategic location and critical role in flood risk reduction, SCS-Roaring Creek Site-D3 serves as an important water resource management infrastructure in Oklahoma. As a key element in the state's regulatory framework, this dam highlights the ongoing efforts to mitigate the impact of extreme weather events and ensure the safety of surrounding communities. As climate change continues to pose challenges, the maintenance and monitoring of structures like SCS-Roaring Creek Site-D3 become increasingly vital in safeguarding against potential hazards and enhancing resilience in the face of evolving environmental conditions.

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.
