Leggett Number 1 Dam dam
Leggett Number 1 Dam
The Leggett Number 1 Dam, located in Jones, Mississippi, stands as a testament to both engineering ingenuity and environmental stewardship. Completed in the year 2000, this earth dam with a height of 15 feet serves primarily for recreational purposes, providing a tranquil oasis for locals and visitors alike. With a storage capacity of 277 acre-feet and a surface area of 32.24 acres, the dam plays a crucial role in managing water resources in the area.
Owned privately but regulated by the Mississippi Department of Environmental Quality, the Leggett Number 1 Dam boasts a moderate hazard potential, with a risk assessment rating of 3 out of 5. The dam's spillway type is uncontrolled, with a maximum discharge capacity of 84 cubic feet per second. While its condition is currently not rated, the dam undergoes regular inspections and is subject to state enforcement and permitting processes, ensuring its continued safety and functionality for years to come.
For water resource and climate enthusiasts, the Leggett Number 1 Dam represents a harmonious blend of human intervention and natural beauty. Its presence along the Channel Branch not only enhances the local landscape but also contributes to the sustainable management of water resources in the region. As climate change continues to impact our environment, structures like the Leggett Number 1 Dam play a vital role in adapting to and mitigating the challenges posed by a changing climate, making it a noteworthy site for those passionate about water conservation and environmental protection.

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 Leggett Number 1 Dam
Where does the data for Leggett Number 1 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 Undetermined 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.
