Lake Walthall Dam dam
Lake Walthall Dam
Located in Walthall, Mississippi, Lake Walthall Dam is a state-owned structure with a primary purpose of recreation. Built in 1965, this earth dam stands at 35 feet in height and spans 1170 feet in length, creating a reservoir with a storage capacity of 1549 acre-feet. The dam regulates the flow of the UNT of Kirklin Creek and has a maximum discharge capacity of 6052 cubic feet per second.
Despite being classified as having an undetermined hazard potential and a moderate risk level, Lake Walthall Dam is not currently rated for its condition. The Mississippi Department of Environmental Quality oversees the regulation, permitting, inspection, and enforcement of this dam, ensuring its safety and functionality for recreational activities in the area. With its picturesque surroundings and ample surface area of 37 acres, the dam provides a popular spot for outdoor enthusiasts and nature lovers to enjoy water-based activities.
While the dam does not have associated locks or outlet gates, its spillway type is uncontrolled. The New Orleans District of the US Army Corps of Engineers does not have involvement in the ownership, funding, design, construction, regulation, inspection, or operation of Lake Walthall Dam. As climate change continues to impact water resources and ecosystems, maintaining the safety and integrity of structures like Lake Walthall Dam is crucial for sustainable water management and environmental conservation efforts in Mississippi.

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 Lake Walthall Dam
Where does the data for Lake Walthall 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.
