Hartwell Dam - Saddle Dike 1 dam
Hartwell Dam - Saddle Dike 1
Hartwell Dam - Saddle Dike 1 is a key structure located in Hart, Georgia, along the Savannah River, designed by CESAS and owned by the US Army Corps of Engineers. This Federal-owned dam, completed in 1962, serves primarily for hydroelectric purposes, with additional benefits including flood risk reduction, recreation, and water supply. With a dam height of 34 feet and a storage capacity of over 3 million acre-feet, this structure plays a crucial role in managing water resources in the region.
Despite its essential function, Hartwell Dam - Saddle Dike 1 poses a high hazard potential, prompting the implementation of Emergency Action Plans (EAP) to ensure swift and effective response in case of emergencies. The dam has undergone regular inspections, with the last one conducted in April 2017, and meets the necessary guidelines for risk assessment and management. Inundation maps have been prepared, and risk mitigation measures are in place, highlighting the commitment to ensuring the safety and stability of this vital infrastructure for both water resource management and climate resilience in the area.
As a significant component of the US Army Corps of Engineers' operations, Hartwell Dam - Saddle Dike 1 stands as a testament to the agency's dedication to maintaining critical water infrastructure. With a focus on safety, risk assessment, and emergency preparedness, this dam plays a crucial role in harnessing the power of water resources while safeguarding against potential hazards, making it a cornerstone for water resource and climate enthusiasts in the region.

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 Hartwell Dam - Saddle Dike 1
Where does the data for Hartwell Dam - Saddle Dike 1 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.
