Summary

Completed in 1970, this earth dam stands at a height of 20.2 feet with a hydraulic height of 17 feet. The dam offers a maximum storage capacity of 105.2 acre-feet, with a normal storage level of 52.2 acre-feet across its 450-foot length.

Despite being classified as having a low hazard potential, Hill Lake Dam is subject to state jurisdiction and inspection to ensure its structural integrity and safety measures are up to standard. With a moderate risk assessment rating, the dam has not been officially rated for its condition. The last inspection was conducted in June 2018, with an inspection frequency of every 5 years to monitor any potential risks or hazards associated with the dam.

Located within the Lorane Environs of Monroe, Georgia, Hill Lake Dam serves as a key recreational asset for the surrounding community, offering opportunities for outdoor activities and water-based leisure. Its picturesque setting, combined with its moderate risk assessment, makes Hill Lake Dam an intriguing site for water resource and climate enthusiasts to explore and study in the context of dam safety and management.

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.
