Jennings Creek #16 dam
Jennings Creek #16
Jennings Creek #16, also known as Jennings Creek Watershed Dam 16, is a crucial structure located in Macon, Tennessee, owned by the local government and designed by the USDA NRCS. This earth dam, completed in 1960, serves the primary purpose of flood risk reduction on the Donoho Hollow river or stream. With a hydraulic height of 22 feet and a structural height of 47.1 feet, the dam provides significant storage capacity of 409 acre-feet, helping to mitigate potential flooding in the area.
The dam's condition is assessed as satisfactory, with a hazard potential rated as significant. Regular inspections conducted by the Tennessee Safe Dams Program ensure the dam's structural integrity and safety compliance. Despite its age, Jennings Creek #16 continues to effectively manage flood risk in the region, with its moderate risk assessment indicating a manageable level of potential hazard. The dam's operations are not managed by the USACE, but rather by local authorities, highlighting the community's commitment to water resource management and climate resilience.
As a key component in the local flood risk reduction strategy, Jennings Creek #16 plays a vital role in safeguarding North Springs and surrounding areas from potential flooding events. With its stone core and rock and soil foundations, the dam stands as a testament to effective engineering design and ongoing maintenance efforts. The dam's association with the Tennessee Safe Dams Program ensures that it meets regulatory standards and continues to provide essential protection to the community, making it a crucial asset for water resource and climate enthusiasts to monitor and appreciate.

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 #16
Where does the data for Jennings Creek #16 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.
