Smiley - Henry dam
Smiley - Henry
Smiley - Henry is a privately owned dam located in Culpeper, Virginia, along the TR-Thorton River. This earth dam serves the primary purpose of irrigation, with a height of 29 feet and a length of 350 feet. With a storage capacity of 81 acre-feet, it plays a crucial role in providing water for agricultural activities in the region.
Managed by the Department of Conservation and Recreation in Virginia, Smiley - Henry is regulated, permitted, inspected, and enforced by the state agency to ensure its safety and compliance with regulations. Although its hazard potential is currently undetermined and its condition is not rated, the dam serves as a vital water resource infrastructure for the local community. Its location within the Baltimore District and its association with the TR-Thorton River make it a key component in the water management system of the area.
While details about its construction year, modifications, and maintenance history are not available, Smiley - Henry remains an essential structure for water resource management in the region. With its capacity to store water for irrigation purposes and its role in supporting agriculture, this dam contributes to the sustainability and resilience of the local water supply system. As water resource and climate enthusiasts, understanding the significance of structures like Smiley - Henry is crucial for appreciating the interconnectedness of water management and environmental stewardship.
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.

About Smiley - Henry
Where does the data for Smiley - Henry 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.
