Twin Oaks Plantation Lake Dam dam
Twin Oaks Plantation Lake Dam
Twin Oaks Plantation Lake Dam, located in Thomasville, Georgia, was completed in 1957 and serves multiple purposes including fire protection, stock, and small fish pond maintenance. The dam, standing at a height of 15.8 feet with a hydraulic height of 13.2 feet, has a storage capacity of 141.8 acre-feet and covers a surface area of 14 acres. Despite its low hazard potential and moderate risk assessment rating, the dam is unregulated by the state and lacks official inspections and enforcement measures.
Owned privately, Twin Oaks Plantation Lake Dam is primarily made of earth with a buttress core type and an uncontrolled spillway. The dam's design and construction details remain unknown, reflecting a lack of regulatory oversight and documentation. While the dam's condition assessment is listed as "Not Rated," its last inspection in August 2019 indicated a low hazard potential. The dam's emergency action plan status and risk management measures are also unspecified, raising questions about its safety and preparedness.
With its location in Thomasville, Georgia, Twin Oaks Plantation Lake Dam presents a unique case study for water resource and climate enthusiasts. The dam's historical significance, multi-functional purpose, and lack of regulatory oversight highlight the complexities of managing and maintaining water infrastructure in a changing climate. As efforts to address dam safety and resilience continue to evolve, Twin Oaks Plantation Lake Dam serves as a reminder of the importance of proactive monitoring and maintenance to protect communities and ecosystems from potential risks and impacts.

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 Twin Oaks Plantation Lake Dam
Where does the data for Twin Oaks Plantation Lake 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.
