Summary
Designed by USDA NRCS and completed in 1961, this earth dam stands at a height of 38 feet and has a hydraulic height of 34 feet. With a storage capacity of 445 acre-feet and a normal storage of 94 acre-feet, this dam plays a crucial role in managing the flow of the TR-Washita River.
Despite being classified as having a low hazard potential, SCS-Upper Washita Creek Site-038 is deemed to have a very high risk factor. The dam features a controlled spillway with a width of 1 foot and one valve outlet gate. While the condition assessment is marked as "not rated", the last inspection date dates back to January 1980, indicating a need for updated evaluations. The dam site is situated in Cheyenne, with its risk management measures, emergency action plan, and inundation maps status currently unknown.
Water resource and climate enthusiasts will find SCS-Upper Washita Creek Site-038 to be an intriguing case study in dam infrastructure and risk assessment. As a vital component in flood risk reduction for the region, this dam's design, construction, and regulatory oversight provide valuable insights into the challenges and considerations of managing water resources in Oklahoma. The data reveals both the importance of these structures in safeguarding communities from potential disasters and the ongoing need for thorough monitoring and maintenance to ensure their continued effectiveness.

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.
