Jennings Creek #15 dam
Jennings Creek #15
Jennings Creek #15, also known as Jennings Creek Watershed Dam 15, is a critical water resource infrastructure located in Jackson, Tennessee. Constructed in 1961 by the USDA NRCS, this earth dam stands at a structural height of 44.7 feet and serves the primary purpose of flood risk reduction along the Hudson Hollow river or stream. With a hydraulic height of 20.2 feet and a NID storage capacity of 254 acre-feet, this dam plays a significant role in managing water flow and protecting the surrounding areas from potential flooding events.
Managed by the Tennessee Safe Dams Program, Jennings Creek #15 is regulated, inspected, and enforced to ensure its structural integrity and safety. The dam's hazard potential is rated as high, but its condition assessment as of December 2020 was deemed satisfactory. Despite its moderate risk level, the dam has not undergone recent modifications and lacks emergency action plans, highlighting the need for continued monitoring and risk management measures to safeguard the community and environment in case of emergencies.
Given its crucial role in flood risk reduction and water management, Jennings Creek #15 remains a vital asset for the local government in North Springs, Tennessee. With a drainage area of 0.76 square miles and a normal storage capacity of 37 acre-feet, this dam contributes to the overall resilience of the region against potential water-related disasters. As climate change continues to impact weather patterns and precipitation levels, the proper maintenance and monitoring of this dam are essential to ensure the safety and well-being of the community it serves.

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 Jennings Creek #15
Where does the data for Jennings Creek #15 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.
