Bosher Dam dam
Bosher Dam
Bosher Dam, located on the James River in Henrico, Virginia, serves as a crucial water supply infrastructure managed by the local government. This gravity dam stands at a height of 10 feet with a storage capacity of 2100 acre-feet, providing essential water resources for the region. While the dam is state regulated and inspected, its hazard potential and condition assessment remain undetermined, emphasizing the need for ongoing monitoring and maintenance to ensure its operational integrity.
The primary purpose of Bosher Dam is water supply, reflecting its vital role in ensuring a reliable water source for the community. Despite its modest height, the dam plays a significant role in managing the flow of the James River and storing water for various uses. As a state-regulated structure, Bosher Dam falls under the jurisdiction of the Department of Conservation and Recreation, highlighting the importance of compliance with safety and regulatory standards to safeguard both the dam and the surrounding environment.
With its location on the James River and its key role in water supply infrastructure, Bosher Dam stands as a testament to the efforts to manage and preserve water resources in Virginia. As climate change impacts water availability and quality, the maintenance and operation of dams like Bosher Dam become even more critical in ensuring a sustainable and resilient water supply for the region. Through continued monitoring, inspection, and risk assessment, Bosher Dam can continue to fulfill its essential function in supporting the community's water needs while adapting to evolving environmental 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 Bosher Dam
Where does the data for Bosher 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 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.
