South River Dam #7 dam
South River Dam #7
South River Dam #7, also known as Wilda, is a crucial flood risk reduction structure located in Augusta, Virginia. Managed by the local government, this earth dam stands at a height of 46 feet and spans 763 feet in length, providing storage capacity of 690 acre-feet. With a hazard potential rated as high, the dam's condition assessment as of February 2020 was deemed satisfactory, signaling its structural integrity and readiness to withstand potential flood events.
Situated on the TR-South River, this dam is under the jurisdiction of the Virginia Department of Conservation and Recreation, ensuring state-regulated permitting, inspection, and enforcement processes are in place. Despite its age of completion not being specified, South River Dam #7 continues to serve its primary purpose of flood risk reduction with a normal storage capacity of 19 acre-feet. With a history of regular inspections and a hazard potential of high, this dam remains a crucial component of water resource management in the region.
Climate and water resource enthusiasts will be captivated by the intricacies of South River Dam #7, from its design and construction to its ongoing regulatory oversight and operational efficiency. As part of the flood risk reduction strategy for the area, this dam plays a vital role in safeguarding communities against potential inundation events, showcasing the importance of proactive management and maintenance of critical infrastructure in the face of changing environmental conditions and climate challenges.

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 South River Dam #7
Where does the data for South River Dam #7 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.
