Hattiesburg Lagoon Dam dam
Hattiesburg Lagoon Dam
The Hattiesburg Lagoon Dam in Mississippi is a locally owned structure that serves a vital role in water resource management. This earth dam, with a height of 18 feet, has a low hazard potential but is regulated by the Mississippi Department of Environmental Quality. Despite not being rated for its condition, the dam provides a storage capacity of 3,080 acre-feet and has a moderate risk assessment rating of 3.
Located in Forrest County, Mississippi, the Hattiesburg Lagoon Dam does not have associated structures or outlet gates. Its primary purpose is categorized as "Other," with an uncontrolled spillway type. The dam's risk management measures and emergency action plan status are currently unspecified, highlighting the need for continued monitoring and evaluation to ensure the safety and efficiency of this important water infrastructure.
For water resource and climate enthusiasts, the Hattiesburg Lagoon Dam represents a significant piece of Mississippi's water management infrastructure. With its low hazard potential and moderate risk assessment rating, the dam plays a crucial role in storing water and mitigating potential flooding risks in the region. Moving forward, ongoing inspections, assessments, and emergency preparedness measures will be essential to maintain the integrity and functionality of this key earth dam.

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 Hattiesburg Lagoon Dam
Where does the data for Hattiesburg Lagoon 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.
