Summary
Completed in 1970, this dam stands at a height of 22 feet with a hydraulic height of 19 feet and a structural height of 22 feet. With a storage capacity of 76 acre-feet, this dam plays a crucial role in managing water flow and reducing the risk of flooding in the area.
Despite its low hazard potential, the dam has a very high risk assessment rating, indicating the importance of regular inspections and maintenance. The last known inspection dates back to 1980, with a scheduled inspection frequency of 5 years. While the condition assessment is currently not rated, the dam is equipped with a controlled spillway and a valve outlet gate to manage water flow effectively. The dam's primary purpose is flood risk reduction, highlighting its significance in protecting the surrounding communities from potential water-related disasters.
As a vital part of the state's water resource infrastructure, SCS-Upper Washita Creek Site-104 serves as a reminder of the importance of sustainable water management practices in mitigating climate change impacts. With its role in flood risk reduction and water flow regulation, this dam showcases the collaborative efforts of government agencies like the OWRB and NRCS in safeguarding communities and ecosystems against the adverse effects of extreme weather events.

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.
