Summary
With a height of 40 feet and a maximum storage capacity of 460 acre-feet, this dam serves as a vital water resource structure in the region. The dam's spillway type is controlled, with a width of 1 foot, ensuring efficient water flow management during peak discharge events.
Despite being assessed as having fair structural condition in 2011, the dam at SCS-Washington Creek Site-1 poses a high hazard potential, emphasizing the importance of regular inspections and maintenance. The risk assessment classifies the site as having a very high risk level, underscoring the need for robust risk management measures. With a designated emergency action plan and high-risk designation, this site is closely monitored to mitigate potential risks and ensure the safety of surrounding communities and ecosystems.
The dam's primary purpose, as classified by the USDA NRCS, is listed as "Other," indicating its role in various water resource management activities. The site's association with the Natural Resources Conservation Service highlights its importance in environmental conservation efforts. With a history of federal funding and oversight, SCS-Washington Creek Site-1 stands as a crucial infrastructure asset in Garvin County, Oklahoma, contributing to water supply, flood control, and environmental protection initiatives in the region.

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.
