Summary

Completed in 1960, this dam stands at a height of 40 feet and has a hydraulic height of 36 feet, with a max storage capacity of 249 acre-feet. With a controlled spillway and a single valve outlet gate, this dam serves its primary purpose effectively while also providing a surface area of 13 acres for water storage.

Despite being categorized as having a low hazard potential, SCS-Upper Washita Creek Site-052 is considered to have a very high risk rating, emphasizing the need for proper risk management measures. The dam has not been inspected since 1980, highlighting the importance of regular inspections to assess its condition and ensure its continued effectiveness in flood risk reduction. With the dam being located within the jurisdiction of the Oklahoma Water Resources Board, it is subject to state permitting, inspection, and enforcement to maintain its structural integrity and protect the surrounding area from potential flooding risks.

For water resource and climate enthusiasts, SCS-Upper Washita Creek Site-052 presents an intriguing case study of a state-regulated earth dam designed for flood risk reduction in Oklahoma. With its historical significance dating back to 1960 and its unique design features such as a controlled spillway and valve outlet gate, this dam serves as a vital infrastructure for managing water flow and protecting the local community from potential flooding events. However, the dam's lack of recent inspections and high-risk rating emphasize the need for proactive risk management measures to ensure its continued safety and functionality in the face of changing climate patterns and water resource dynamics.

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.
