Summary
Constructed in 1964 by USDA NRCS, this dam serves the primary purpose of grade stabilization along the TR-W.BR.S.FK.BLACKWATER river. With a height of 20 feet and a length of 885 feet, the dam has a storage capacity of 228 acre-feet and covers a surface area of 6 acres.
Despite being classified as low hazard potential, the dam poses a moderate risk level and has not been rated for its condition assessment. With no outlet gates and an uncontrolled spillway type, the dam is designed to withstand a maximum discharge of 290 cubic feet per second. While it has not been inspected recently, the dam remains in operation and has not undergone any modifications since its completion.
For water resource and climate enthusiasts, South Fork Blackwater River Dam A-24 offers an intriguing case study in dam engineering and management. Its presence in the Kansas City District highlights the importance of maintaining infrastructure for grade stabilization in rural areas. With a moderate risk level, the dam presents an opportunity for further assessment and potential improvements to ensure its long-term safety and effectiveness in water resource management.

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.
