Blasingame #3 dam
Blasingame #3
Located in McNairy, Tennessee, Blasingame #3 is a privately owned earth dam constructed in 1987 primarily for irrigation purposes. 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.

Condition Assessment
- Satisfactory
- No 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.
- 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.
- 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.
Hazard Potential Classification
- High
- Dams 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, environmental 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.

About Blasingame #3
Where does the data for Blasingame #3 come from?
Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.
How often is the report updated?
NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.
What does the Low hazard rating mean?
The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.
What's "% of normal"?
The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).
Can I get alerts when storage crosses a threshold?
Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.
