Betty Whitman Dunn Dam Dam
Betty Whitman Dunn Dam
Betty Whitman Dunn Dam, located in Abbeville, South Carolina, is a private earth dam completed in 1948 with a height of 18 feet and a length of 225 feet. It serves as a crucial structure on TR-BOWMAN BRANCH, providing storage capacity of 62 acre-feet for water resource management. The dam's primary purpose is listed as "Other," indicating its importance beyond flood control or irrigation.
Despite being privately owned, Betty Whitman Dunn Dam falls under the jurisdiction of the Savannah District of the US Army Corps of Engineers. With its hazard potential labeled as "Undetermined" and condition assessment as "Not Rated," the dam's safety and maintenance are crucial for the surrounding community's well-being. The last inspection in January 2018 highlighted the need for regular assessments and emergency preparedness measures.
Water resource and climate enthusiasts will be intrigued by the unique design of Betty Whitman Dunn Dam, its historical significance, and the potential impact it has on the local ecosystem and water management. As a key structure in the area, its upkeep and monitoring are essential for ensuring the safety and sustainability of the surrounding environment and communities that rely on its services.

About Betty Whitman Dunn Dam
Where does the data for Betty Whitman Dunn 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 Undetermined 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.
Dam data reference
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.
