Summary
The dam sits on TR Dry Creek and serves the primary purpose of flood risk reduction, with a height of 26 feet and a length of 2420 feet. It has a storage capacity of 680 acre-feet and a drainage area of 1.8 square miles, making it a crucial structure for managing water resources in Stephens County.
The dam is equipped with a controlled spillway and a single valve outlet gate for water release. Despite being assessed as in fair condition in 2011, it poses a significant hazard potential due to its location and capacity, with a very high risk rating. The dam is subject to regular inspections by the Oklahoma Water Resources Board and meets state permitting, inspection, and enforcement requirements. With the potential for high discharge rates and a history of modification for flood risk reduction, SCS-Cow Creek Site-46 remains a key feature in the region's water resource management infrastructure.
For water resource and climate enthusiasts, SCS-Cow Creek Site-46 represents a vital piece of the puzzle in mitigating flood risks and managing water flow in the Stephens County area. Its design by the USDA NRCS and state regulation ensure that it plays a critical role in safeguarding the local community against potential flooding events. With its significant hazard potential and very high risk rating, ongoing monitoring and maintenance are essential to ensure the dam's continued effectiveness in protecting the surrounding area from water-related emergencies.

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.
