Hartwell Dam - Saddle Dike 2 dam
Hartwell Dam - Saddle Dike 2
Hartwell Dam - Saddle Dike 2, located in Hart, Georgia, is a crucial structure within the Savannah River watershed managed by the US Army Corps of Engineers. Completed in 1962, this earth dam stands at 36 feet tall and spans 1840 feet, serving primarily for hydroelectric power generation. With a maximum storage capacity of 3,438,700 acre-feet and a normal storage of 2,550,000 acre-feet, the dam plays a key role in flood risk reduction, water supply, recreation, and fish and wildlife conservation in the region.
Despite its importance, Hartwell Dam - Saddle Dike 2 poses a high hazard potential, prompting regular inspections every 5 years to ensure its structural integrity. Emergency action plans have been prepared and updated to meet established guidelines, with inundation maps in place for risk assessment and management. The dam, with its stone core type, plays a critical role in water resource management within the region, highlighting the significance of its operations and maintenance by the US Army Corps of Engineers.
In the face of climate change and increasing water resource challenges, the significance of Hartwell Dam - Saddle Dike 2 as a key infrastructure for the Savannah River cannot be understated. As a focal point for hydroelectric power generation and multiple water management purposes, the dam underscores the importance of sustainable water resource management practices and proactive risk mitigation measures to ensure the safety and resilience of the surrounding communities and ecosystems in the face of evolving climatic conditions.

About Hartwell Dam - Saddle Dike 2
Where does the data for Hartwell Dam - Saddle Dike 2 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 below 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.

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.
