Summary

Signal Community in Shelby, Alabama, was completed in 1977 for the primary purpose of recreation. This privately owned earth dam stands at a structural height of 40 feet, with a hydraulic height of 35 feet and a length of 220 feet. The dam has a normal storage capacity of 476 acre-feet, providing ample water resources for recreational activities such as boating, fishing, and swimming.

Despite not being state regulated or permitted, Girl Scout Lake Dam has a significant hazard potential, posing a potential risk to the surrounding area in the event of a breach. The dam's condition has not been rated, and there is no emergency action plan in place. With a maximum discharge capacity of 1290 cubic feet per second, it is crucial for stakeholders to monitor and assess the dam's structural integrity to ensure the safety of both the dam and the local community.

As water resource and climate enthusiasts, it is important to recognize the vital role that dams like Girl Scout Lake Dam play in providing recreational opportunities and water storage. By staying informed about the condition and potential risks associated with dams, we can work towards sustainable management practices that protect both the environment and local communities.

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.
