Summary
3 is a private water resource located in Jefferson County, Alabama, near the city of Graysville. With a dam height of 25 feet and a maximum discharge capacity of 320 cubic feet per second, this impoundment plays a significant role in water management in the region. While the primary purpose and specific design features of the dam are not specified in the data, its hazard potential is deemed significant, highlighting the importance of proper maintenance and oversight.
Despite being privately owned and not regulated by the state, Impoundment No. 3 is a crucial component of the local water infrastructure. Its condition is currently not rated, indicating a need for further assessment and potentially the development of an Emergency Action Plan (EAP) to address any potential risks associated with the dam. The lack of state jurisdiction and permitting raises questions about the level of oversight and regulation for this impoundment, especially in the face of changing climate patterns and increasing water resource challenges.
As water resource and climate enthusiasts, understanding the intricacies of impoundments like No. 3 allows for a more comprehensive view of how human activities intersect with natural systems. The data provided offers a glimpse into the complexities of managing water resources, highlighting the need for sustainable practices and robust regulatory frameworks to ensure the safety and longevity of such structures. Further research and monitoring will be crucial to fully grasp the implications of Impoundment No. 3 on the local ecosystem and community, underscoring the interconnectedness of water management and climate resilience.

Dam Data Reference
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.
