Summary
This earth dam, standing at a height of 28.7 feet with a hydraulic height of 24.4 feet, serves various purposes including fire protection, stock, and a small fish pond. The dam has a storage capacity of 76 acre-feet, with a normal storage level of 43 acre-feet, covering a surface area of 4.7 acres and draining an area of 84 acres.
Although the dam has a low hazard potential and is currently not rated for its condition, it is subject to regular inspections with a frequency of 5 years. The last inspection was conducted in June 2019, ensuring the safety and integrity of the structure. Hattaway Lake Dam features an uncontrolled spillway system and outlet gates, contributing to its moderate risk assessment level. Despite being a private-owned dam, it plays a crucial role in the local ecosystem and water resource management in the area.
With its unique design and multiple purposes, Hattaway Lake Dam stands as a significant landmark in Clay County, Georgia. Its strategic location and function make it an essential element in the region's water resource infrastructure. As climate change continues to impact water resources, structures like Hattaway Lake Dam will play a vital role in maintaining water quality and availability for the surrounding community.

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.
