Moss Mine #1 Dam
Moss Mine #1 Dam
Moss Mine #1 Dam, located in Dickenson, Virginia, is a crucial water resource structure that serves a primary purpose not listed, with a dam height of 154 feet and a storage capacity of 1314 acre-feet. The dam is situated on the Lick Fork river and falls under the jurisdiction of the Mine Safety and Health Administration for regulatory oversight and inspections. Despite being classified as undetermined in terms of hazard potential, the condition assessment of Moss Mine #1 Dam is currently not rated.
With a lack of information on the year of completion and other structural details such as dam length and volume, Moss Mine #1 Dam remains a bit of a mystery for water resource and climate enthusiasts. The dam does not have a designated primary dam type and is categorized as "Other" in terms of dam types. Although the dam does not have a designated inspection frequency, it is essential to recognize its significance in the region and the potential impact it may have on the surrounding environment in the event of failure.
As an integral part of the water infrastructure in the area, Moss Mine #1 Dam's role in water storage and management cannot be understated. With a focus on safety and risk assessment, further evaluation and monitoring of the dam's condition and hazard potential are crucial to ensuring the protection of downstream communities and the environment. Despite its uncertain hazard potential and condition assessment, Moss Mine #1 Dam stands as a vital structure in the region's water resource management efforts, deserving of continued attention and oversight.

About Moss Mine #1 Dam
Where does the data for Moss Mine #1 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.
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.
