Summary
Morrison Dam No.2 is a private-owned structure located in Hale, Alabama, specifically in the city of St. Thomas Church. Built in 1970, this earth-type dam serves primarily for recreational purposes along Polecat Creek, with a hydraulic height of 34 feet and a structural height of 37 feet. The dam has a storage capacity of 190 acre-feet and a maximum discharge of 875 cubic feet per second. Although it is not regulated by the state, the dam is considered to have a significant hazard potential, yet its condition assessment is currently not rated.
Despite having no associated structures or outlet gates, J.L. Morrison Dam No.2 poses a significant risk due to its location and purpose. The dam's emergency action plan status is unknown, and there are no existing inundation maps or risk assessment measures in place. With its close proximity to the community and the potential for flooding events, it is crucial for stakeholders and authorities to prioritize the safety and maintenance of this dam to prevent any potential disasters. In light of the current lack of regulation and assessment, further evaluation and risk management measures should be considered to ensure the safety of the surrounding area and water resources.

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.
