King William County Dam #12 dam
King William County Dam #12
King William County Dam #12, located in King William, Virginia, is a state-regulated dam under the jurisdiction of the Department of Conservation and Recreation. With a height of 10 feet and a length of 450 feet, this dam serves a primary purpose that is not specified in the available data. It has a storage capacity of 62.8 acre-feet and a normal storage level of 12 feet, providing essential water resource management in the area.
Despite its critical role in water management, the hazard potential of King William County Dam #12 is currently undetermined, and its condition assessment is not rated. The dam has not been inspected in recent years, but it is subject to state permitting, inspection, and enforcement, ensuring its safety and compliance with regulations. The dam's emergency action plan status and risk assessment measures are not specified in the data, leaving some aspects of its management and safety procedures unclear.
For water resource and climate enthusiasts, King William County Dam #12 presents an intriguing case study in the complex world of dam infrastructure and regulation. With its unique characteristics and location in the Norfolk District, this dam embodies the intersection of human engineering with natural resources, highlighting the importance of proper maintenance, inspection, and emergency preparedness in the face of changing climate conditions. As efforts continue to enhance the safety and sustainability of dams like King William County Dam #12, it serves as a reminder of the ongoing challenges and opportunities in managing water resources for the benefit of communities and the environment.

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 King William County Dam #12
Where does the data for King William County Dam #12 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.
