About this dam

Giles Dam

Located in Pittsylvania, Virginia, Giles Dam stands as a vital water resource infrastructure along the GREEN ROCK BRANCH river. With a primary purpose of irrigation, this earth dam boasts a height of 21 feet and a storage capacity of 51 acre-feet. Despite its significance in water management, its hazard potential remains undetermined, with a condition assessment that is yet to be rated. Operated and regulated by the Department of Conservation and Recreation in Virginia, Giles Dam ensures the sustainable use of water for agricultural purposes in the region.

While the exact year of completion remains unknown, Giles Dam continues to play a crucial role in maintaining water security in the area. Although not rated for condition assessment, the dam undergoes regular inspections to ensure its structural integrity and operational efficiency. With a storage capacity of 51 acre-feet, the dam serves as a lifeline for irrigation in the region, ensuring a reliable water supply for agricultural activities along the GREEN ROCK BRANCH river.

As water resource and climate enthusiasts, Giles Dam presents an intriguing case study in water management and infrastructure development. Operating under the jurisdiction of the Department of Conservation and Recreation in Virginia, this earth dam underscores the importance of sustainable water use for agricultural purposes. With its storage capacity and strategic location, Giles Dam stands as a critical asset in ensuring water security and resource management in Pittsylvania, 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.

FAQ

About Giles Dam

Where does the data for Giles 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.
