Summary
This dam on TR Ramar Creek has a hydraulic height of 20 feet, a structural height of 22 feet, and a length of 880 feet. With a storage capacity of 121 acre-feet, it serves as a low hazard potential structure with a not rated condition assessment.
Despite being a privately owned dam, Arrington No 1 is not regulated or inspected by the state of Alabama. Its primary source agency is the AL (Alabama) and it falls under the jurisdiction of the Mobile District of the US Army Corps of Engineers. The dam's maximum discharge is 263 cubic feet per second, and it has not been modified since its completion.
Water resource and climate enthusiasts interested in the infrastructure of dams will find Arrington No 1 an intriguing case study. The dam's historical significance, purpose, and structural details make it a noteworthy feature in the water management landscape of Alabama. Its location in the picturesque city of Troy Chapel adds to the charm of exploring this unique piece of engineering.

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.
