Summary
Built in 1972 by the USDA NRCS, this Earth-type dam stands at 36 feet tall with a hydraulic height of 32 feet and a length of 490 feet. Its primary purpose is flood risk reduction, providing a storage capacity of 154 acre-feet and a maximum discharge of 1984 cubic feet per second.
Despite being classified as a low hazard potential structure, the dam at Washita County State School Land is considered to have a very high risk due to its location and the potential consequences of failure. The dam is regulated by the OWRB and undergoes regular state inspections and enforcement measures to ensure its safety and compliance with regulations. Although its condition assessment is currently deemed as not rated, the dam's risk management measures and emergency action plan status are not specified in the available data.
Overall, Washita County State School Land serves as a crucial infrastructure for flood risk reduction in the region, with its design and construction overseen by the Natural Resources Conservation Service. As water resource and climate enthusiasts, the data on this dam provides valuable insights into its specifications, regulatory framework, and risk assessment, highlighting the importance of maintaining and monitoring such critical infrastructure to safeguard communities and the environment from potential disasters.

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.
