Rex Haven Lake Dam (Lower) dam
Rex Haven Lake Dam (Lower)
Rex Haven Lake Dam (Lower) in Monticello, Georgia, is a privately owned earth dam constructed in 1945 for recreational purposes. Standing at a height of 28 feet with a hydraulic height of 27 feet, this dam spans a length of 665 feet and has a storage capacity of 531 acre-feet. The dam's primary purpose is to provide recreational opportunities, with a surface area of 36 acres and a normal storage capacity of 396 acre-feet.
Although the dam has a low hazard potential and is currently rated as "Not Rated" in terms of condition assessment, it undergoes inspections every five years to ensure its safety and integrity. The last inspection was conducted in November 2018. Despite not being regulated by the state, the dam is subject to periodic inspections to monitor its risk level, which is currently classified as moderate. With an uncontrolled spillway and outlet gates, the dam poses minimal risk to the surrounding area, making it a popular destination for water resource and climate enthusiasts seeking a serene recreational spot in Jasper County, Georgia.
Located in the Mobile District of the US Army Corps of Engineers, Rex Haven Lake Dam (Lower) is a testament to the collaboration between private owners and regulatory agencies to maintain a safe and enjoyable water resource for the community. As an essential part of the local landscape, this dam provides not only recreational opportunities but also serves as a reminder of the importance of sustainable water management practices in the face of changing climate conditions. With a rich history dating back to its construction in the mid-20th century, this dam continues to be a valuable asset for both residents and visitors alike in the heart of Georgia's beautiful countryside.
Dam data reference
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 Rex Haven Lake Dam (Lower)
Where does the data for Rex Haven Lake Dam (Lower) 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.
