Summary
Completed in 1998, this Earth type dam stands at a height of 16 feet, with a hydraulic height of 18 feet and a length of 500 feet. It has a storage capacity of 72 acre-feet and serves the purpose of debris control in addition to flood risk reduction. The dam's spillway, with a width of 12 feet, is of the uncontrolled type.
Managed and funded by the US Army, Sediment Basin No.3 plays a crucial role in protecting the surrounding area from potential flooding risks. While the dam's hazard potential is deemed low, its condition assessment is currently not available, with the last inspection taking place in March 2017. Despite its moderate risk rating, the dam has not been subject to any modifications in recent years, highlighting its robust design and construction.
With its strategic location near Tributary Casey Creek and associations with the Louisville District of the US Army, Sediment Basin No.3 serves as a vital piece of infrastructure in safeguarding the community against flood hazards. Its role in maintaining water resources and climate resilience underscores the importance of continual monitoring and maintenance to ensure its effectiveness in mitigating potential risks.

Dam Data Reference
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.
