Summary
Built in 1955 for recreational purposes, the dam has a structural height of 30 feet and a hydraulic height of 25 feet, with a storage capacity of 65 acre-feet. The dam spans 520 feet in length and has a maximum discharge capacity of 450 cubic feet per second, making it a low hazard potential structure with a condition assessment of "Not Rated".
Despite being privately owned, Coley is not regulated by the state of Alabama and does not fall under state jurisdiction for permitting, inspection, or enforcement. The dam is not monitored by any federal agency and has not been modified in recent years. While the dam does not have an emergency action plan in place or updated inundation maps, it is considered to have a low risk assessment and currently does not have any risk management measures in place.
Overall, Coley serves as a recreational structure in the MT VIEW CHURCH COMMUNITY, providing opportunities for outdoor activities in the region. With its historical significance and modest storage capacity, the dam remains a staple in the area for water resource and climate enthusiasts to explore and appreciate.

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.
