O E Rose Dam dam
O E Rose Dam
O E Rose Dam, located in Clarendon, South Carolina, stands as a testament to water resource management and irrigation infrastructure dating back to 1900. This private earth dam on Mill Branch is crucial for irrigation purposes, with a storage capacity of 719 acre-feet and a normal storage level of 600 acre-feet. Despite its age, the dam remains a significant structure, although its condition assessment is currently rated as poor, indicating potential maintenance needs.
Managed by the South Carolina Department of Health and Environmental Control, the O E Rose Dam has a height of 15 feet and a length of 412 feet, serving as a vital resource for the surrounding area. The dam's poor condition and significant hazard potential highlight the importance of ongoing inspections and risk management measures to ensure its continued functionality. As climate change impacts water resources, maintaining infrastructure like O E Rose Dam will be essential for sustainable water management in the region.
With Congressman James E. Clyburn representing the area in the US House of Representatives, the O E Rose Dam plays a crucial role in supporting agricultural activities and water supply in Clarendon County. As water resource and climate enthusiasts, understanding the history and current status of dams like O E Rose is essential for advocating for sustainable water management practices and investing in infrastructure resilience to address future challenges posed by a changing climate.

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 O E Rose Dam
Where does the data for O E Rose 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.
