Summary
Managed by the local government, this earth dam structure was completed in 1967 with a primary purpose of recreation. However, it also serves as a water supply source for the surrounding area, showcasing the multiple benefits of this water resource.
With a dam height of 47 feet and a hydraulic height of 44 feet, Mastersom Mill Lake has a maximum storage capacity of 1890 acre-feet. The reservoir sits along Turkey Creek and covers a surface area of approximately 633 feet, making it a popular spot for outdoor activities such as fishing, boating, and picnicking. Despite its high hazard potential, the condition of the dam is currently not rated, highlighting the need for ongoing maintenance and monitoring.
As an essential part of the local ecosystem and community, Mastersom Mill Lake provides not only recreational opportunities but also ensures a reliable water supply for the area. With its tranquil setting and rich history dating back to the 1960s, this reservoir continues to be a valuable asset for water resource and climate enthusiasts in Lawrence, Alabama.

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.
