Rex Haven Lake Dam (Upper) dam
Rex Haven Lake Dam (Upper)
Located in Monticello, Georgia, Rex Haven Lake Dam (Upper) is a privately owned structure designed by King in 1930 for recreational purposes. This earth dam stands at a height of 17 feet and has a hydraulic height of 16 feet, with a storage capacity of 200 acre-feet and a surface area of 20 acres. Despite being unregulated by the state, the dam has a low hazard potential and a moderate risk assessment rating.
The dam features an uncontrolled spillway and outlet gates, with no associated structures or locks. While its condition is currently not rated, the last inspection conducted in November 2018 determined a low hazard potential. The dam's risk management measures and emergency action plans are not specified, highlighting the need for further assessment and preparation in case of unforeseen events.
For water resource and climate enthusiasts, Rex Haven Lake Dam (Upper) serves as a historical and recreational landmark in Jasper County. Its unique design and purpose, coupled with its moderate risk assessment rating, make it an intriguing subject for further study and analysis in the realm of water resource management and climate resilience. This dam not only provides valuable recreational opportunities but also presents challenges and opportunities for enhancing its safety and sustainability in the face of potential hazards.

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 (Upper)
Where does the data for Rex Haven Lake Dam (Upper) 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.
