Summary
With a hydraulic height of 7 feet and a structural height of 9 feet, Allison spans 650 feet in length and has a storage capacity of 83 acre-feet. Despite its low hazard potential and not being rated for condition assessment, Allison remains a significant landmark in the area, offering opportunities for outdoor activities and water-based recreation.
Situated in Congressional District 03, Alabama, Allison is under the jurisdiction of the Mobile District of the US Army Corps of Engineers. While the dam does not have state regulation, permitting, inspection, or enforcement, it serves as a valuable resource for the local community and visitors alike. With a maximum discharge of 53 cubic feet per second, Allison contributes to the overall water management and conservation efforts in the region, ensuring a sustainable balance between human needs and environmental preservation.
Although lacking specific details on its design and construction, Allison stands as a testament to the ingenuity and engineering prowess of its time, providing a glimpse into the history of water resource development in Alabama. As climate change continues to impact water availability and quality, structures like Allison play a crucial role in maintaining resilience and adaptability in the face of evolving environmental challenges. Whether for leisure or practical purposes, Allison remains a symbol of human interaction with nature and the ongoing efforts to steward our water resources for future generations.

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.
