Summary

Constructed in 2001 by the USDA NRCS, this earth-type dam serves the primary purpose of flood risk reduction along the tributary to Little Deep Red Creek. With a structural height of 20.7 feet and a length of 6400 feet, the dam has a storage capacity of 5855 acre-feet and a drainage area of 7.03 square miles.

Managed by the Oklahoma Water Resources Board (OWRB), this dam boasts a controlled spillway type and a low hazard potential, with a very high risk assessment ranking. While the dam is currently in a not-rated condition, it is subject to state permitting, inspection, and enforcement to ensure its continued safety and effectiveness in flood control. Although no associated structures or modifications have been reported, the dam remains a crucial asset in mitigating flood risks in the region.

Overall, SCS-Middle Deep Red Run Watershed Site7b stands as a vital infrastructure piece in the water resource management system of Oklahoma, playing a crucial role in protecting nearby communities from potential flooding events. As climate change continues to impact weather patterns and water availability, the proper regulation and maintenance of such dams are essential in safeguarding both the environment and local populations from the increasing threats of extreme weather and water-related disasters.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
