Moore Dam dam
Moore Dam
Moore Dam, also known as Davis Dam and formerly named Williams Dam, is a private-owned structure located in Patrick, Virginia. This earth dam stands at 29 feet tall with a length of 175 feet, providing recreational opportunities along the tributary to Mayo River. Despite being designated for recreation, the dam's hazard potential is currently undetermined, and its condition is not rated, with the last inspection dating back to September 2004.
Managed by the Department of Conservation and Recreation in Virginia, Moore Dam serves as a crucial part of the state's regulatory framework, with permits, inspections, and enforcement in place to ensure its safety and integrity. The dam has a storage capacity of 41 acre-feet, primarily used for recreational purposes. While specifics about its spillway type, maximum discharge, and outlet gates are not provided, the dam's location and purpose make it a key feature in the water resource management and climate adaptation efforts in the region.
With its proximity to the Mayo River and surrounding areas, Moore Dam plays a vital role in supporting water activities, wildlife habitats, and flood control measures. As climate change impacts continue to affect water resources, the maintenance and monitoring of structures like Moore Dam become even more critical. By staying updated on its condition, emergency action plans, and risk assessment measures, water resource and climate enthusiasts can contribute to the sustainable management of this essential infrastructure in Virginia.

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 Moore Dam
Where does the data for Moore 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.
