Bob's #1 dam
Bob's #1
Bob's #1 is a privately owned earth dam located in Maury, Tennessee, near the city of Porters Chapel. Built in 1961, this dam stands at a structural height of 40.6 feet and has a hydraulic height of 37.1 feet, with a total length of 723 feet. The dam has a storage capacity of 434 acre-feet and serves the purpose of regulating the flow of TribScotts Creek.
Despite being classified as a high-hazard potential structure with a moderate risk assessment, Bob's #1 has not been rated for its condition. The dam has not undergone recent inspections, with the last one taking place in January 2017. While there are no associated locks or spillways with the structure, it is crucial to ensure regular maintenance and monitoring to prevent any potential risks or hazards. Water resource and climate enthusiasts should keep a close eye on the status of Bob's #1 and advocate for necessary safety measures to protect the surrounding community and environment.
In the event of an emergency, it is important for the owners of Bob's #1 to have an Emergency Action Plan (EAP) in place to mitigate any potential risks or threats. With a lack of detailed risk management measures and assessment summaries, there is room for improvement in ensuring the safety and stability of this dam. Continued oversight and proactive measures will be essential to safeguard the integrity of Bob's #1 and uphold the critical role it plays in water resource management in the region.
Dam data reference
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 Bob's #1
Where does the data for Bob's #1 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 High 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.
