Summary
Built in 1959, this dam serves multiple purposes including fire protection, stock, small fish pond, and recreation. With a hydraulic height of 14 feet and a structural height of 19 feet, this dam has a storage capacity of 190 acre-feet and a normal storage level of 126 acre-feet.
Situated on the TR Line Creek, Gerald Wallace No 1 spans 650 feet in length and has a maximum discharge capacity of 2100 cubic feet per second. Despite being classified as a low hazard potential structure, this dam has not been rated for condition assessment. The dam is not under state jurisdiction and is not regulated or inspected by any state agency. The emergency action plan for this dam has not been prepared or updated, raising concerns about its readiness in case of an emergency.
Water resource and climate enthusiasts will find Gerald Wallace No 1 an intriguing structure due to its multi-purpose utility and location in the picturesque surroundings of Tysonville, Alabama. The dam's historical significance, lack of state oversight, and potential risks associated with its emergency preparedness make it a noteworthy subject for further study and monitoring in the realm of water resource management and climate resilience.

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.
