Summary

# 1, also known as Trophy Club Lake, is a state-owned earth dam located in Gwinnett, Georgia. Built in 1967 by the Natural Resources Conservation Service, this dam serves the primary purpose of flood risk reduction along the No Business Creek. Standing at a height of 42 feet and with a length of 585 feet, this dam has a storage capacity of 2400 acre-feet and covers a surface area of 27 acres, with a drainage area of 2614 acres.

This dam is regulated by the Georgia Safe Dams Program and undergoes regular inspections, with the last assessment conducted in January 2016 revealing a satisfactory condition. Despite being classified as having a high hazard potential, the risk assessment for No Business Creek WS Str. # 1 is moderate with a rating of 3. While no emergency action plan or inundation maps have been prepared for this structure, it remains an essential component in managing flood risk in the area and ensuring the safety of nearby communities.

Located in the jurisdiction of Centerville, Georgia, this dam plays a crucial role in protecting the surrounding area from flooding. With its historical significance dating back to the 1960s, No Business Creek WS Str. # 1 stands as a testament to the importance of water resource management and climate resilience in the face of increasing natural disasters.

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.
