Summary

Built in 1964, this dam stands at a height of 53 feet with a length of 730 feet, providing a storage capacity of 2232 acre-feet and a normal storage level of 142 acre-feet. The dam covers a surface area of 21 acres and serves a drainage area of 7.84 square miles, with a maximum discharge capacity of 3050 cubic feet per second.

Managed by the USDA NRCS, Tobesofkee Creek 41 is essential in mitigating flood risks in the region, with a significant hazard potential and moderate risk assessment rating. While the condition assessment is currently not available, the dam undergoes inspections every five years to ensure its structural integrity and safety. With an uncontrolled spillway type and a width of 500 feet, the dam plays a crucial role in flood management and protection of the local community.

Water resource and climate enthusiasts will find Tobesofkee Creek 41 an intriguing structure, given its historical significance, engineering design, and impact on flood risk reduction in Monroe County, Georgia. The dam's construction and operation by the Natural Resources Conservation Service highlight the importance of sustainable water management practices in safeguarding communities against potential water-related disasters. As a key component of the local flood control system, Tobesofkee Creek 41 exemplifies the collaborative efforts between government agencies and stakeholders to enhance water resource resilience and protect the environment.

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.
