Summary
Built in 1978, this earth dam serves multiple purposes including fire protection, stock, and a small fish pond, with additional recreational opportunities. With a hydraulic height of 16 feet and a structural height of 27.5 feet, the dam has a storage capacity of 66 acre-feet and covers a surface area of 7 acres.
Despite its low hazard potential, Blasingame #1 has a moderate risk assessment rating. The dam's condition is currently not rated, and its last inspection took place in October 2018. While the dam's emergency action plan status is unclear, it is important to note that the structure lacks outlet gates and has an uncontrolled spillway type. With a drainage area of 0.23 square miles, the dam plays a crucial role in managing water resources in the area.
For water resource and climate enthusiasts, Blasingame #1 offers a fascinating case study in dam infrastructure and management. Its location along Snake Creek highlights the importance of sustainable water management practices in Tennessee. As efforts to address climate change intensify, understanding and monitoring structures like Blasingame #1 will be crucial in ensuring the safety and resilience of water resources in the region.

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.
