Summary

Completed in 1995, this earth dam primarily serves the purpose of recreation, offering a tranquil escape for water resource and climate enthusiasts. The dam boasts a height of 16 feet and a length of 836 feet, creating a reservoir with a normal storage capacity of 99 acre-feet and a surface area of 18.25 acres.

Despite being classified as low hazard potential and having a moderate risk assessment rating, Marion Hamm Lake Dam is an important feature along the UNT of Town Creek, with an uncontrolled spillway type and a hydraulic height of 16 feet. The dam's condition assessment has not been rated, but its risk management measures are in place to ensure the safety of the surrounding community. With a designated emergency action plan and updated contact information, the dam is prepared for any unforeseen events, providing a sense of security for those who enjoy its recreational offerings.

Supported by the Mobile District of the US Army Corps of Engineers, Marion Hamm Lake Dam stands as a reliable structure that enriches the local environment and offers a peaceful retreat for visitors. Its design as an earth dam with buttress core types reflects a blend of functionality and aesthetics, while its modest storage capacity and controlled release measures ensure its resilience in the face of changing weather patterns and water levels. For water resource and climate enthusiasts, Marion Hamm Lake Dam is not just a structure but a symbol of responsible stewardship and recreation in harmony with nature.

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.
