Toano Dam dam
Toano Dam
Toano Dam, located in James City, Virginia, is a vital irrigation structure with a primary purpose of supplying water for agricultural needs. The dam, standing at a height of 23 feet, provides a storage capacity of 186 acre-feet for efficient water management in the region. Situated on a tributary of Mill Creek, this earth dam plays a crucial role in supporting the local farming community by ensuring a reliable water supply for irrigation.
Despite its importance for irrigation, Toano Dam's hazard potential is currently listed as undetermined, with its condition assessment marked as not rated. The dam's emergency action plan status, risk assessment, and management measures are yet to be fully evaluated and documented. However, the dam's location and purpose signify its significance in sustaining agricultural activities in the area, highlighting the need for continued monitoring and assessment to ensure its reliability and safety for water resource management.
As a key infrastructure for water resource management in the region, Toano Dam serves not only irrigation purposes but also offers recreational opportunities for the local community. With its strategic location and storage capacity, the dam contributes to the economic and social well-being of the area. As the dam's condition and risk factors remain to be fully assessed, ongoing efforts are crucial to safeguard its functionality and safety for both water resource management and recreational activities in the region.

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 Toano Dam
Where does the data for Toano 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.
