Nearby: Scs-Cow Creek Site-38 Williams R.E.
Last Updated: December 22, 2025
Located in Stephens, Oklahoma, the SCS-Cow Creek Site-39, also known as Cow Creek Site-39, is a state-regulated earth dam designed by the USDA NRCS in 1960 for the primary purpose of flood risk reduction along the TR Dry Creek.

Summary
This dam stands at 25 feet high with a hydraulic height of 22 feet, providing a maximum storage capacity of 80 acre-feet and a normal storage level of 43 acre-feet. With a surface area of 15 acres, this controlled spillway dam features a single valve outlet gate for water management.
Despite its low hazard potential, the SCS-Cow Creek Site-39 has not been rated for its condition assessment, and the last inspection was conducted in 1980. The risk assessment for this dam is categorized as very high, with a DSAC not assigned date and limited information on risk management measures. While the emergency action plan status is unclear, the site's compliance with inspection, permitting, and enforcement regulations by the state regulatory agency OWRB underscores its commitment to safe and effective water resource management in Oklahoma.

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.
