Summary
With a structural height of 37.1 feet and a length of 940 feet, this dam has a normal storage capacity of 144 acre-feet and a maximum storage capacity of 198 acre-feet. The reservoir covers a surface area of 15 acres and drains an area of 0.1 square miles, providing water for fire protection, livestock, and small fish ponds in addition to irrigation.
Despite its low hazard potential, Blasingame #3 has a moderate risk assessment rating of 3, indicating a need for ongoing monitoring and risk management measures. The dam is classified as uncontrolled spillway type with no outlet gates, and has not been rated for its condition. The last inspection took place in October 2018, with a scheduled inspection frequency of every 5 years. While the dam has not been regulated or permitted by the state, it plays a crucial role in water resource management in the region.
Blasingame #3 is situated on Tribsnake Creek and falls under the jurisdiction of the Memphis District of the US Army Corps of Engineers. With its historical significance as a key irrigation infrastructure in the area, this dam serves as a vital resource for agricultural activities and contributes to the overall water ecosystem in Tennessee. Climate and water resource enthusiasts will find this structure to be a fascinating example of human intervention in natural water systems, highlighting the importance of sustainable water management practices for the future.

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.
