Scs-Cow Creek Site-03 Reservoir Report

Last Updated: December 5, 2025

SCS-Cow Creek Site-03, located in Waurika, Oklahoma, is a state-regulated earth dam designed by the USDA NRCS in 1978 for the primary purpose of flood risk reduction along the TR-Monument Creek.

Summary

The dam stands at a height of 22 feet and has a hydraulic height of 19 feet, with a length of 940 feet and a storage capacity of 423 acre-feet. Despite being rated as having a high hazard potential, the dam's condition is assessed as fair, and it is equipped with a controlled spillway and a single valve outlet gate.

With a very high risk assessment rating, the SCS-Cow Creek Site-03 dam is under the jurisdiction of the OWRB in Jefferson County, Oklahoma. Although it has not been modified in recent years, the dam undergoes inspections annually to ensure its operational integrity. While the emergency action plan (EAP) status and risk management measures are not specified, the dam is considered to be in fair condition and meets state regulatory standards for permitting, inspection, and enforcement. For water resource and climate enthusiasts, SCS-Cow Creek Site-03 presents an intriguing case study in dam safety and flood risk mitigation efforts in the region.

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.
