Summary
With a height of 30 feet and a storage capacity of 169 acre-feet, this dike plays a significant role in managing water resources in the area. Despite its high hazard potential, the dike is currently assessed to be in fair condition as of the last inspection in April 2017.
The reservoir serves multiple purposes such as flood control, irrigation, and water supply, making it an essential component of the region's water infrastructure. With a surface area of 12.7 acres and a normal storage capacity of 113 acre-feet, the Columbia Reservoir Dike plays a crucial role in ensuring water security for the surrounding communities. The dike is subject to regular inspections and enforcement by state agencies, highlighting the importance of its maintenance and upkeep to prevent potential risks.
As a key structure in the Savannah District, the Columbia Reservoir Dike stands as a testament to the intricate network of dams and dikes that contribute to water management and climate resilience in the region. With its strategic location and significant storage capacity, this dike is a vital piece of infrastructure that plays a pivotal role in safeguarding against floods and ensuring a reliable water supply for local residents.

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.
