Summary

Completed in 1980, this earth dam stands at 13 feet high and spans 200 feet in length, with a storage capacity of 52 acre-feet. The dam boasts a spillway width of 19 feet and a maximum discharge of 90 cubic feet per second, making it a key feature for water resource management in the area.

With a low hazard potential and fair condition assessment, Atlanta Sportsmen Dam is an essential component of the local water infrastructure. It is regularly inspected, with the last assessment conducted in July 2016, ensuring its safety and functionality for the surrounding community. Despite its moderate risk rating, the dam continues to provide valuable recreational opportunities while contributing to water storage and management efforts in Montmorency County.

Located in a picturesque setting and offering a surface area of 10 acres, Atlanta Sportsmen Dam is a popular spot for outdoor enthusiasts and climate advocates alike. Its importance in maintaining water resources and mitigating potential risks underscores the significance of responsible dam management and the crucial role these structures play in sustainable water management practices.

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.
