Sweet Water Reservoir Report

Last Updated: April 1, 2026

Sweet Water, also known as Lewis Pond Dam, is a private recreational water resource located in Marengo, Alabama.


Summary

Built in 1966, this dam spans 655 feet and stands at a structural height of 32 feet, with a hydraulic height of 29 feet. The primary purpose of Sweet Water is for recreation, offering a serene environment for enthusiasts to enjoy activities such as fishing and boating on the Lewis Branch stream.

Despite its significant hazard potential, Sweet Water has not been rated for its condition assessment, and it does not fall under state regulation or jurisdiction. The dam has a storage capacity of 116 acre-feet, with a normal storage level of 108 acre-feet. In the event of an emergency, there is no detailed Emergency Action Plan (EAP) in place, raising questions about the preparedness and risk management measures for this water resource.

Located in Congressional District 07 of Alabama, Sweet Water serves as a vital recreational spot within the region. With its picturesque setting and ample storage capacity, this dam provides a valuable oasis for water and climate enthusiasts to appreciate and enjoy. However, the lack of comprehensive inspection and emergency planning underscores the importance of ensuring the safety and sustainability of this important water resource.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
