Summary
Built in 1968, the earth dam stands at a structural height of 28 feet and has a hydraulic height of 27 feet. With a storage capacity of 126 acre-feet, the dam serves as a crucial water resource for the surrounding area, particularly in cases of emergency.
The dam is situated on TR Pinchony Creek and is under the jurisdiction of the Mobile District of the US Army Corps of Engineers. Despite its low hazard potential, Wallock Dam has not been rated for its condition assessment, and its emergency action plan status remains unknown. The dam's maximum discharge capacity is 200 cubic feet per second, ensuring adequate water management during heavy rainfall events. For water resource and climate enthusiasts, Wallock Dam presents an intriguing case study of a small-scale structure with significant implications for local water supply and management.
As Martha Roby (R) represents Congressional District 02, Alabama, where Wallock Dam is located, the dam plays a vital role in ensuring water security for the community. Its multiple purposes, including recreation, highlight the importance of small-scale water infrastructure in supporting various societal needs. Moving forward, continued monitoring and assessment of Wallock Dam will be essential to ensure its long-term functionality and resilience in the face of changing climate patterns and water resource demands.

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.
