King William County Dam #3 dam
King William County Dam #3
King William County Dam #3 is a privately owned dam located in King William, Virginia. This dam is regulated by the Department of Conservation and Recreation and is subject to state permitting, inspection, and enforcement. With a height of 12 feet and a length of 650 feet, this dam has a storage capacity of 182.16 acre-feet and a normal storage of 9.3 acre-feet.
Although the hazard potential of King William County Dam #3 is undetermined and its condition is not rated, the dam is subject to regular inspections with a frequency of one inspection per year. The Emergency Action Plan (EAP) status and risk assessment for this dam are currently not available. The dam does not have a spillway type specified, and information on associated structures, last inspection date, and condition assessment date is also not provided.
Located in a picturesque setting in King William County, this dam presents an intriguing case for water resource and climate enthusiasts to delve deeper into its history, design, and current regulatory status. As a part of the Norfolk District, this dam serves as a vital infrastructure for water management in the region, highlighting the intersection of engineering, environmental conservation, and regulatory oversight in safeguarding water resources. Further research and analysis of King William County Dam #3 could provide valuable insights into the challenges and opportunities in managing water resources amidst changing climate conditions.

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 #3
Where does the data for King William County Dam #3 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.
