Summary
The dam, with a high hazard potential, is situated on the TR-Hallmark Creek Tributary 4, within the jurisdiction of the Mobile District of the US Army Corps of Engineers. Despite its important purposes, the dam's condition remains unrated, with no recent inspection or assessment data available.
The dam's construction year, height, volume, and storage capacity are not specified in the data, suggesting a lack of detailed information on its physical characteristics. However, its high hazard potential underscores the importance of regular inspections and risk management measures to ensure the safety of surrounding communities and downstream areas. With no state regulation or permitting in place, it is crucial for the private owner to prioritize safety measures and emergency preparedness for this vital water resource.
Given the critical role of Johnson Farm Lake Dam in fire protection and water storage, stakeholders and climate enthusiasts should advocate for increased monitoring, maintenance, and risk assessment protocols to safeguard the dam's integrity and prevent potential disasters. Collaboration between the private owner, federal agencies, and local authorities is essential to ensure the resilience and sustainability of this important water infrastructure in Blount County, 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.
