Scs-Salt Creek Site-18 Reservoir Report

Last Updated: December 17, 2025

SCS-Salt Creek Site-18, located in Trousdale, Oklahoma, is a state-regulated earth dam constructed in 1961 by the USDA NRCS with a primary purpose of flood risk reduction along the TR-WOLF CREEK.

Summary

Standing at a height of 19 feet and a length of 1050 feet, this dam has a storage capacity of 189 acre-feet and a spillway type of controlled. Despite its low hazard potential, the risk assessment for this dam is rated very high, indicating the importance of proper management and maintenance to ensure its effectiveness.

Owned and regulated by the Oklahoma Water Resources Board (OWRB), SCS-Salt Creek Site-18 has not been inspected since January 1980, with an assigned inspection frequency of 5 years. The condition of the dam is currently not rated, and there is no emergency action plan (EAP) in place. With a risk assessment of very high (1), there is a need for increased attention and monitoring of this structure to mitigate potential hazards and ensure its continued functionality in protecting the surrounding area from flooding events.

As water resource and climate enthusiasts, it is crucial to recognize the significance of structures like SCS-Salt Creek Site-18 in managing water flow and mitigating flood risks in vulnerable areas. With its state-regulated status and high-risk assessment, there is a clear need for continued oversight, maintenance, and potentially the development of an updated emergency action plan to address any potential hazards. By staying informed and advocating for the proper management of such infrastructure, we can contribute to the preservation of water resources and the protection of communities in flood-prone regions.

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.
