Hidden Valley Estates Dam dam
Hidden Valley Estates Dam
Hidden Valley Estates Dam, located in Grayson, Virginia, is a privately owned earth dam with a primary purpose of recreation. Standing at a height of 28.4 feet and stretching 550 feet in length, this dam holds a maximum storage capacity of 134 acre-feet and covers a surface area of 10 acres. The dam overlooks the tributary Peach Bottom Creek and is regulated by the Department of Conservation and Recreation in Virginia.
With a high hazard potential, Hidden Valley Estates Dam underwent its last inspection in August 2021 and was deemed to be in satisfactory condition. The dam has a state-regulated status with required permitting, inspection, and enforcement measures in place to ensure its safety and integrity. Designed by Froehling and Robertson, Inc., this dam provides a recreational oasis for water resource and climate enthusiasts in the area.
As a key feature in the Wilmington District, Hidden Valley Estates Dam serves as both a functional structure and a picturesque destination for those seeking outdoor activities. Its tranquil surroundings and carefully monitored condition make it an important asset for the community, highlighting the importance of responsible dam management in preserving water resources and enhancing recreational opportunities in the region.
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.

About Hidden Valley Estates Dam
Where does the data for Hidden Valley Estates 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 High 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.
