Summary
Standing at a height of 28 feet and a length of 430 feet, it has a storage capacity of 567 acre-feet for water management. The dam features an uncontrolled spillway with a width of 112 feet and has a low hazard potential with moderate risk assessment due to its limited water storage capacity.
Managed by the US Army Corps of Engineers, Shelbyville Dam is subject to regular inspections and maintenance to ensure its structural integrity and functionality. The dam's risk management measures involve continuous monitoring, prioritization of activities to mitigate risks, and collaboration with local emergency managers for emergency preparedness and response. Updates to the emergency action plan and engagement with the public are key components of risk management to address potential flood risks associated with the dam.
In the face of severe weather events and varying water levels, Shelbyville Dam plays a crucial role in managing water flow to prevent flooding and maintain safety. The USACE's proactive approach to risk assessment and management underscores the importance of maintaining the dam's operations and implementing necessary measures to safeguard the surrounding community and environment from potential hazards.

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.
