Blue Ridge School Dam dam
Blue Ridge School Dam
Blue Ridge School Dam, located in Greene, Virginia, serves a primary purpose of irrigation along the Roach River. This private dam stands at 30 feet in height and spans 460 feet in length, with a storage capacity of 89 acre-feet. Despite its fair condition assessment in 2015, the hazard potential remains undetermined, highlighting the importance of regular inspections and maintenance to ensure the safety and functionality of the structure.
Managed by the Department of Conservation and Recreation in Virginia, Blue Ridge School Dam is subject to state regulation, inspection, and enforcement. The dam is situated in a picturesque location, offering essential water resource management for agricultural purposes in the region. Although the year of completion is unknown, the dam plays a crucial role in supporting irrigation activities and water storage needs along the Roach River.
With Denver Riggleman representing the area in Congress and the Baltimore District overseeing its management, Blue Ridge School Dam stands as a vital infrastructure for water resource enthusiasts and climate advocates. As climate change continues to impact water availability and usage, the preservation and proper maintenance of dams like Blue Ridge School are essential for sustainable water management practices in the region.

About Blue Ridge School Dam
Where does the data for Blue Ridge School 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.
