Fortieth Place Dam dam
Fortieth Place Dam
Located in Hattiesburg, Mississippi, Fortieth Place Dam is a privately owned structure with a primary purpose of recreation. Completed in 1995, this Earth dam stands at 27 feet tall and spans 300 feet in length, providing a storage capacity of 150 acre-feet. The dam regulates the flow of Gordon Creek and offers a surface area of 10 acres for outdoor activities.
Maintained by the Mississippi Department of Environmental Quality, Fortieth Place Dam has a high hazard potential but is currently in satisfactory condition. Regular inspections are conducted, with the last assessment performed in December 2020. Despite its moderate risk assessment, the dam's emergency action plan meets guidelines, ensuring preparedness in case of unforeseen events. With a controlled spillway and a maximum discharge capacity of 725 cubic feet per second, this dam serves as a vital recreational resource while also prioritizing safety and environmental conservation.
For water resource and climate enthusiasts, Fortieth Place Dam represents a harmonious blend of human recreation and environmental stewardship. This structure not only provides recreational opportunities but also plays a crucial role in managing water flow and storage in the region. With a focus on safety and risk management, the dam serves as a model for sustainable infrastructure development, showcasing the importance of balancing human needs with environmental considerations in water resource management.

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 Fortieth Place Dam
Where does the data for Fortieth Place 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 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.
