Summary
Completed in 1954, this earth dam stands at a structural height of 20 feet with a hydraulic height of 14 feet. It boasts a storage capacity of 200 acre-feet, with a normal storage level of 140 acre-feet. The dam spans 700 feet in length and has a maximum discharge of 1200 cubic feet per second.
Despite being privately owned, L and M has a significant hazard potential and is not currently rated for its condition. The dam does not fall under state jurisdiction and is not regulated or inspected by state agencies. However, it is situated in Congressional District 03 of Alabama, represented by Mike Rogers (R). The dam does not have an emergency action plan in place and has not been assessed for risk management measures.
For water resource and climate enthusiasts, L and M presents an intriguing case of a privately owned recreational dam with limited oversight and regulatory involvement. Its historical significance as a recreational structure in Alabama adds to its allure, while its potential hazards raise questions about its current condition and emergency preparedness. Further research and assessment may shed light on the sustainability and safety of this dam for the surrounding community and environment.

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.
