Summary
Standing at a height of 28.9 feet with a hydraulic height of 25 feet, this dam has a normal storage capacity of 77 acre-feet and a maximum storage of 99.5 acre-feet. The dam spans 405 feet in length and covers a surface area of 7 acres.
Although the dam is not state regulated, it undergoes regular inspections, with the last one conducted in July 2009. Classified as having a low hazard potential and a moderate risk assessment, Arnold Lake Dam is currently in a condition that is not rated. Despite its uncontrolled spillway and outlet gates, the dam has been identified as a recreational asset for the area, offering opportunities for water resource and climate enthusiasts to enjoy the surrounding landscape and activities.
As a structure within the Mobile District of the US Army Corps of Engineers, Arnold Lake Dam presents a unique opportunity for individuals interested in water resource management and climate resilience to study a privately owned recreational dam in a rural setting. With its peaceful surroundings and moderate risk assessment, this dam provides a glimpse into the intersection of human-made infrastructure and natural water systems, making it a valuable site for further exploration and research in the field.

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.
