Summary
7, located in Whitfield, Georgia, is an Earth type dam constructed in 1961 by the Natural Resources Conservation Service for the primary purpose of Flood Risk Reduction along Mill Creek. This structure has a dam height of 31.3 feet and a hydraulic height of 26.8 feet, with a length of 960 feet and a storage capacity of 1937 acre-feet. Despite having a low hazard potential and being classified as in "Not Rated" condition, it is subject to regular inspections, with the last one conducted in February 2018.
The dam features an uncontrolled spillway and outlet gates, and is recognized for its moderate risk level. The surrounding area, known as the Hassler Mill Community, benefits from the flood protection provided by Structure No. 7. While the dam is not under the jurisdiction of the state regulatory agency, it is inspected by the state and meets guidelines for emergency action plans, although specific details on such plans are not provided. With its historical significance and ongoing function in mitigating flood risks, Mill Creek Watershed Structure No. 7 stands as a testament to the importance of sustainable water resource management in safeguarding communities and ecosystems.

Dam Data Reference
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.
