Summary

Standing at a height of 35 feet with a hydraulic height of 20 feet, the dam boasts a storage capacity of 28 acre-feet and covers a surface area of 2 acres. The dam, constructed with a buttress core type, has been classified with a low hazard potential and a moderate risk assessment.

Despite being privately owned, the dam is subject to state inspection and regulation, ensuring its structural integrity and safety. The last inspection of Silver Ridge Lake Dam took place in November 1996, with an inspection frequency of every 5 years. The dam is equipped with an uncontrolled spillway and outlet gates, and while the condition assessment is currently listed as "not rated," the risk assessment categorizes the dam as having a moderate risk level.

For water resource and climate enthusiasts, Silver Ridge Lake Dam presents an intriguing case study in private dam ownership and management. With its recreational focus and moderate risk level, the dam serves as a valuable asset within the DeKalb County community, showcasing the importance of regular inspections and maintenance to ensure its continued safety and functionality in the face of potential environmental challenges.

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.
