Harvey Shaw Dam dam
Harvey Shaw Dam
Harvey Shaw Dam, located in Lee, South Carolina, stands as a significant earth dam that was completed in 1950. With a height of 10 feet and a length of 500 feet, the dam boasts a storage capacity of 78 acre-feet, primarily serving the purpose of recreation. The dam, situated on the TR-Black River, is privately owned and regulated by the South Carolina Department of Health and Environmental Control.
Despite its fair condition assessment as of January 2019, Harvey Shaw Dam poses a significant hazard potential due to its location and structural elements. With an inspection frequency of three years, the dam is regularly monitored to ensure its integrity and safety. The emergency action plan (EAP) status and risk assessment for the dam are currently unspecified, raising questions about the level of preparedness in case of a potential hazard event.
Enthusiasts of water resources and climate may find Harvey Shaw Dam to be a compelling subject of study, given its historical significance, structural design, and regulatory framework. As a key element in the local water management infrastructure, the dam serves as both a recreational site and a critical component in flood control and water supply management in the region. Further research into the dam's risk management measures, emergency preparedness, and overall impact on the surrounding ecosystem could provide valuable insights into the intersection of water resource management and climate adaptation strategies.

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 Harvey Shaw Dam
Where does the data for Harvey Shaw 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 Significant 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.
