Summary
This earth dam, standing at 27 feet high and stretching 500 feet in length, serves the primary purpose of flood risk reduction along the TR-DRY CREEK. Despite its low hazard potential, the dam boasts a very high risk assessment rating, emphasizing the importance of its role in safeguarding the area from potential inundation.
Owned and regulated by the State of Oklahoma through the OWRB, SCS-Roaring Creek Site-D1 is subject to state permitting, inspection, and enforcement, ensuring its structural integrity and functionality over time. The dam's storage capacity of 156 acre-feet and maximum discharge rate of 465 cubic feet per second further highlight its significance in managing water flow and reducing flood risks in the area. With a controlled spillway and a single valve outlet gate, the dam's design reflects a sound engineering approach to water resource management in the region.
Located in ALEX, Oklahoma, SCS-Roaring Creek Site-D1 serves as a testament to sustainable water resource management practices, as it continues to play a vital role in protecting the surrounding communities from the adverse impacts of flooding. As climate change intensifies, infrastructure like this earth dam becomes even more crucial in ensuring the resilience of the region's water resources and the safety of its inhabitants.

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.
