South River Dam #26 dam
South River Dam #26
South River Dam #26, also known as Inch Branch, 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 57 feet and spans 766 feet in length. With a storage capacity of 868 acre-feet and a drainage area of 2.4 square miles, the dam plays a crucial role in mitigating potential flooding in the area.
Designed by Schnabel Engineering, LLC, South River Dam #26 has been assessed as being in satisfactory condition, with a high hazard potential due to its location and purpose. Regular inspections are conducted to ensure the dam's integrity and effectiveness in safeguarding the surrounding communities. While the dam does not have a designated spillway type or outlet gates, its primary focus remains on flood risk reduction, making it a critical infrastructure for water resource and climate enthusiasts to monitor and appreciate.
As one of the key structures in the Norfolk District, South River Dam #26 serves as a testament to the collaborative efforts between local government agencies and engineering firms in ensuring the safety and resilience of the region against potential water-related disasters. With its strategic placement on the Inch Branch of Back Creek, this dam continues to be a cornerstone in the overall water resource management and climate resilience efforts in Virginia, reflecting the importance of effective infrastructure in safeguarding communities and natural resources.

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 #26
Where does the data for South River Dam #26 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.
