Summary
Pattons Lower Lake Dam, located in the South Easley Community of Blount, Alabama, was completed in 1978 with a primary purpose of recreation. This earth dam stands at a hydraulic height of 28 feet and a structural height of 35 feet, with a length of 650 feet. The dam has a storage capacity of 440 acre-feet and a maximum discharge of 4,320 cubic feet per second, serving as a vital resource for water management and recreational activities along the CWENEY BRANCH river or stream.
Despite being privately owned, Dr. Pattons Lower Lake Dam has a low hazard potential and is currently rated as "Not Rated" in terms of its condition assessment. While it is not regulated by the state or federal agencies, the dam plays a crucial role in providing water storage and recreational opportunities for the local community. The dam's location within the Mobile District of Alabama makes it an important landmark for water resource and climate enthusiasts interested in exploring the diverse ecosystems and landscapes of the region.
As a key feature in the Congressional District 06 of Alabama, Dr. Pattons Lower Lake Dam offers a glimpse into the intersection of human engineering and natural landscapes. With its tranquil surroundings and potential for outdoor activities, the dam serves as a reminder of the importance of sustainable water management practices in the face of changing climate patterns. Its presence highlights the need for continued monitoring and maintenance to ensure the safety and longevity of this essential water resource for future generations to enjoy 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.
