Summary
With a primary purpose of recreation, this earth dam on TR-MAHAN CREEK offers a serene retreat for visitors to enjoy the beauty of nature. Its low hazard potential and not rated condition assessment highlight the careful maintenance and management of this vital structure.
Situated in Chilton County, the J H Oliver Lake Dam boasts a hydraulic height of 23 feet and a structural height of 25 feet, providing essential storage capacity of 92 acre-feet for water conservation. Managed by a private owner, this dam serves as a crucial component in the local ecosystem, supporting the surrounding environment while offering recreational opportunities. The dam's location in Brierfield adds to its appeal as a popular destination for water resource and climate enthusiasts.
With a maximum discharge of 600 cubic feet per second, the J H Oliver Lake Dam ensures the safety and stability of its surroundings. While its emergency action plan and risk assessment details are yet to be fully assessed, the dam's overall design and purpose underscore its significance in the sustainable management of water resources. For those interested in the intersection of water management, climate conservation, and recreational activities, the J H Oliver Lake Dam stands as a prime example of responsible infrastructure development.

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.
