Summary
1, located in Clay, Alabama, is a private recreational dam situated along a tributary of Lynch Creek. Built in 1972, this earth dam stands at a structural height of 14 feet with a hydraulic height of 9 feet. The dam has a storage capacity of 50 acre-feet and a maximum discharge of 720 cubic feet per second, making it a significant structure in the area.
Despite its recreational purpose, Blair No. 1 poses a significant hazard potential due to its condition being currently unrated. The dam has not undergone recent inspections, and there is no emergency action plan in place. With its proximity to residential areas, it is crucial for stakeholders to prioritize assessing and managing the risks associated with this dam to ensure the safety of surrounding communities and the environment.
As water resource and climate enthusiasts, understanding the critical role of infrastructure like Blair No. 1 in water management is essential. By advocating for regular inspections, maintenance, and emergency preparedness measures for dams like Blair No. 1, we can contribute to the sustainable management of water resources and the resilience of communities in the face of changing climate conditions.

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.
