Hell Creek Watershed Structure Lt-9b-5 Dam dam
Hell Creek Watershed Structure Lt-9b-5 Dam
The Hell Creek Watershed Structure Lt-9b-5 Dam, also known as Lt-9b-5, is a local government-owned earth dam located in Tippah, Mississippi, specifically in the city of Punkin Center. Built in 1969 by the USDA NRCS, this dam was designed for flood risk reduction along the Hell Creek river. With a height of 24 feet and a storage capacity of 441 acre-feet, this structure plays a crucial role in regulating water flow in the area.
The dam, made of buttress core and soil foundation, is regulated by the Mississippi Department of Environmental Quality and is inspected regularly for safety and maintenance. Despite its low hazard potential, the dam is considered to have moderate risk due to its age and condition assessment not being rated. The spillway is uncontrolled, and the outlet gates are also uncontrolled, highlighting the need for ongoing monitoring and potential risk management measures to ensure the safety and effectiveness of this vital water resource infrastructure.
For water resource and climate enthusiasts, the Hell Creek Watershed Structure Lt-9b-5 Dam provides an intriguing opportunity to explore the intersection of engineering, environmental regulation, and water management. With its historical significance and continued importance in flood risk reduction, this dam serves as a reminder of the critical role that infrastructure plays in shaping our interactions with the natural world and mitigating the impacts of climate change on local communities.

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 Hell Creek Watershed Structure Lt-9b-5 Dam
Where does the data for Hell Creek Watershed Structure Lt-9b-5 Dam 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.
