Boyle Investment Lake dam
Boyle Investment Lake
Boyle Investment Lake, located in Shelby, Tennessee, is a private earth dam structure on the TRIBWOLF RIVER with a hydraulic height of 19.6 feet and a structural height of 24 feet. Completed in 1948, the dam has a storage capacity of 222 acre-feet and a surface area of 17.8 acres. With a significant hazard potential and a moderate risk assessment rating of 3, this uncontrolled spillway dam poses a potential risk to the surrounding area.
Despite not being regulated or inspected by the state, Boyle Investment Lake remains an important water resource in the Germantown area. The dam has a normal storage capacity of 140 acre-feet and a drainage area of 0.11 square miles. While the condition assessment is marked as "Not Rated," the last inspection in May 2018 revealed no specific concerns. With no outlet gates and no associated structures, the dam's emergency action plan status and risk management measures remain unspecified.
As a popular spot for water and climate enthusiasts, Boyle Investment Lake offers a serene environment for outdoor activities and wildlife observation. With its historical significance dating back to the mid-20th century, the dam serves as a reminder of the importance of water resource management and the need for ongoing monitoring and maintenance to ensure the safety of the community and surrounding areas.

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 Boyle Investment Lake
Where does the data for Boyle Investment Lake 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 Significant 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.
