Summary
30, also known as Seagraves Dam, is a state-owned earth dam located in Fulton County, Georgia. Built in 1960 by the Natural Resources Conservation Service, this dam serves the primary purpose of flood risk reduction in the Crabapple area. With a height of 29.8 feet and a storage capacity of 506 acre-feet, it helps to protect the surrounding area from potential flooding events.
Despite its age, Little River Watershed Structure No. 30 has a low hazard potential and has not been rated for its current condition. However, it is subject to regular inspections every five years to ensure its integrity and safety. The dam features an uncontrolled spillway and outlet gates, with a drainage area of 1293 acres and a normal storage capacity of 169 acre-feet. While the risk assessment for this structure is moderate, its risk management measures and emergency action plan status are not specified in the available data.
Overall, Little River Watershed Structure No. 30 plays a crucial role in managing flood risks in the region, providing important protection for the community. Its design by the SCS and ownership by the state of Georgia highlight the collaborative efforts involved in water resource management and climate resilience. As climate change continues to impact the frequency and intensity of extreme weather events, structures like Seagraves Dam will be essential in safeguarding communities and mitigating potential flood damage.

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.
