Summary

Built in 1964 and primarily designed for recreation, this Earth-type dam stands at a height of 33.7 feet and has a hydraulic height of 25.7 feet. With a drainage area of 354 acres and a storage capacity of 184 acre-feet, the dam covers a surface area of 7.21 acres and serves as a popular spot for outdoor activities.

Despite its satisfactory condition assessment as of February 2019, Morgan Farms Lake Dam has a high hazard potential and is categorized under moderate risk. The dam features an uncontrolled spillway and outlet gates, and is under state regulation, inspection, and enforcement by the Georgia Safe Dams Program. The dam poses a significant risk in case of any failure or emergency, prompting the need for a comprehensive Emergency Action Plan and regular risk management measures to ensure public safety and the integrity of the structure.

With its rich history and significant role in providing recreational opportunities for the community, Morgan Farms Lake Dam stands as a vital water resource in the region. As climate change continues to impact water resources, it is crucial for dam owners and regulatory agencies to prioritize safety measures and maintenance to mitigate risks and ensure the long-term sustainability of this important infrastructure.

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.
