Summary

Constructed in 1965 by USDA NRCS, this Earth-type dam stands at 29 feet tall and spans 890 feet in length. With a maximum storage capacity of 217 acre-feet and a normal storage of 95 acre-feet, the primary purpose of this structure is flood risk reduction in the area.

Managed by the Oklahoma Water Resources Board, SCS-Boggy Creek Site-12a has a low hazard potential and is rated as not yet assessed for condition. Despite being last inspected in 1980, this dam has a controlled spillway with a width of 1 foot and an outlet gate featuring a single valve. While the risk assessment for this site is very high, it remains in operation and meets state regulations for inspection and enforcement.

Though lacking recent data updates and inspections, SCS-Boggy Creek Site-12a continues to serve its primary purpose of flood risk reduction along TR-South Boggy Creek. As a crucial infrastructure in Washita County, Oklahoma, this dam plays a significant role in protecting the surrounding area from potential flooding events, highlighting the importance of ongoing monitoring and maintenance for water resource and climate enthusiasts.

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.
