Summary
Constructed in 1960 by the NRCS, this dam stands at a height of 15 feet and has a storage capacity of 344 acre-feet. Despite being rated as having a low hazard potential, the risk assessment for this dam is very high, indicating the need for continued monitoring and maintenance.
The dam features a controlled spillway with a width of 2 feet and is equipped with a valve outlet gate for water release. Even though the last inspection date was in 1980, the dam has a scheduled inspection frequency of 5 years to ensure its structural integrity and safety. Currently, the condition assessment is listed as not rated, highlighting the importance of regular assessments to address any potential risks and ensure the long-term effectiveness of the flood risk reduction measures in place.
Overall, SCS-Little Washita River Site-31 plays a crucial role in managing flood risks in the area and protecting the surrounding communities from potential inundation. With its strategic location and design, this dam serves as a vital infrastructure asset for water resource management in Oklahoma, highlighting the importance of ongoing monitoring and maintenance to uphold its functionality and safety standards.

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.
