South River Dam #24 dam
South River Dam #24
South River Dam #24, also known as Happy Hollow, is a vital flood risk reduction structure located in Augusta, Virginia. Owned by the local government and regulated by the Department of Conservation and Recreation, this earth dam stands at a height of 35 feet and spans 490 feet in length. With a storage capacity of 330 acre-feet and a drainage area of 1.13 square miles, the dam serves to protect the surrounding area from potential flooding events.
Despite its low hazard potential, South River Dam #24 is maintained in satisfactory condition, as indicated by its last inspection in March 2019. The dam has a normal storage capacity of 13 acre-feet and plays a crucial role in managing the flow of TR-BACK CREEK. While specific details regarding the dam's construction date and spillway type are not provided, its strategic location and design contribute to the overall flood risk reduction efforts in the region.
With its solid structural integrity and history of successful flood risk mitigation, South River Dam #24 serves as a key component in the water resource management strategy of Augusta, Virginia. As climate change continues to impact precipitation patterns and water levels, the importance of well-maintained dams like South River Dam #24 cannot be overstated in safeguarding communities and ecosystems from the threats of flooding.

About South River Dam #24
Where does the data for South River Dam #24 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 Low 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.
