About this dam

Jennings Creek #10

Jennings Creek #10, also known as Jennings Creek Watershed Dam 10, is a vital structure owned by the local government in Jackson, Tennessee. This earth dam, constructed in 1966 by USDA NRCS, serves the primary purpose of flood risk reduction along Crab Tree Creek. Standing at a structural height of 48 feet and a hydraulic height of 17 feet, this dam has a storage capacity of 1487 acre-feet and covers a surface area of 19 acres within a drainage area of 3.64 square miles.

With a hazard potential classified as high and a condition assessment marked as satisfactory during the last inspection in January 2021, Jennings Creek #10 poses moderate risk according to the Tennessee Safe Dams Program. The dam lacks spillway gates and is of uncontrolled spillway type, emphasizing the importance of regular inspections and maintenance to ensure its structural integrity and safety. Despite its critical flood risk reduction role, this dam does not have an Emergency Action Plan (EAP) prepared or updated, highlighting the need for proactive risk management measures and emergency preparedness in the event of a potential breach.

Located in North Springs, Jennings Creek #10 stands as a significant asset in managing water resources and mitigating flood risks in the Jackson area. As climate change impacts continue to influence extreme weather events, the proper maintenance and monitoring of this dam are essential to safeguarding the community and surrounding environment from potential inundation. Through collaboration with regulatory agencies and adherence to inspection protocols, the local government can enhance the resilience of Jennings Creek #10 and ensure its continued effectiveness in protecting against flood disasters.

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.

FAQ

About Jennings Creek #10

Where does the data for Jennings Creek #10 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.
