Menmuir Dam dam
Menmuir Dam
Menmuir Dam, located in Fauquier, Virginia, stands as a testament to private ownership and state regulation in the realm of water resource management. With a structural height of 28 feet and a length of 430 feet, this dam boasts a capacity to store up to 140 acre-feet of water, with a normal storage level of 110 acre-feet. Its undetermined hazard potential and 'Not Rated' condition assessment hint at the need for further evaluation and potential improvements to ensure its safety and functionality.
Managed by the Department of Conservation and Recreation in Virginia, Menmuir Dam is subject to state jurisdiction, permitting, inspection, and enforcement. It is situated within the Baltimore District and falls under the representation of Robert J. Wittman (R) at the Congressional level. While the dam's specific purposes and types are not listed, its presence contributes to the overall water infrastructure in the region, impacting local ecosystems and water resources.
As water resource and climate enthusiasts delve into the details of Menmuir Dam, they are met with a complex web of regulatory oversight, structural specifications, and potential risk factors. The dam's location, design, and storage capacity all play a role in shaping the surrounding environment and community resilience in the face of changing climate conditions. Further exploration and assessment of this infrastructure are essential to ensure its continued effectiveness and safety for both present and future generations.

About Menmuir Dam
Where does the data for Menmuir 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 below 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.

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.
