Poplar Tree dam
Poplar Tree
Poplar Tree is a state-regulated earth dam located in Shelby, Tennessee, near the city of Memphis. Built in 1952, it stands at a structural height of 50.5 feet with a hydraulic height of 34.3 feet and a length of 1360 feet. The dam has a maximum storage capacity of 2255 acre-feet and a drainage area of 1.74 square miles, serving the purpose of water resource management along Dry Bayou.
Despite being classified as having a low hazard potential and being in satisfactory condition, Poplar Tree poses a moderate risk with a rating of 3. Regular inspections are conducted by the Tennessee Safe Dams Program, with the last assessment completed in November 2020. The dam is equipped with an uncontrolled spillway and has no outlet gates. While there are no associated structures or locks, the dam's emergency action plan status and risk management measures are currently undisclosed.
Water resource and climate enthusiasts interested in the operational and safety aspects of dams will find Poplar Tree's data informative. With its historical significance and vital role in managing water resources in the region, this state-regulated earth dam serves as a focal point for understanding the complexities and challenges of maintaining critical infrastructure in the face of evolving climate conditions and environmental risks.

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 Poplar Tree
Where does the data for Poplar Tree 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.
