About this dam

Red Hill Quarry Dam

Red Hill Quarry Dam, also known as Superior Stone Co., is a privately owned structure located in Albemarle, Virginia. Situated along the TR-NORTH FORK HARDWARE RIVER, this earth dam stands at a height of 48.5 feet and has a storage capacity of 1177 acre-feet. The primary purpose of Red Hill Quarry Dam is for recreation, offering a surface area of 38.8 acres for water activities and leisure.

While the dam's condition is assessed as fair, with an undetermined hazard potential, it has not been subject to state regulation, inspection, or enforcement. The Mine Safety and Health Administration oversees regulatory aspects of the dam, with the last inspection conducted in 2010. Despite the lack of state involvement, the dam serves its recreational purpose effectively, with a normal storage capacity of 423 acre-feet and a drainage area of 0.69 square miles.

Water resource and climate enthusiasts interested in Red Hill Quarry Dam can appreciate its role in providing recreational opportunities in the Albemarle region of Virginia. With its serene setting along the river and ample storage capacity, the dam offers a space for outdoor enjoyment and relaxation. While its regulatory oversight may be minimal, the dam continues to serve its intended purpose and enhance the natural landscape for visitors and wildlife alike.

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.

FAQ

About Red Hill Quarry Dam

Where does the data for Red Hill Quarry 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.
