Gilliam Dam dam
Gilliam Dam
Gilliam Dam, located in Bedford, Virginia, is a crucial water resource infrastructure regulated by the Department of Conservation and Recreation. This earth dam stands at a height of 31.5 feet and has a storage capacity of 45.49 acre-feet, with a normal storage level of 27.9 acre-feet. The dam's primary purpose and associated structures are not specified, but its construction and inspection are overseen by the state regulatory agency.
Although the dam's hazard potential is labeled as "Undetermined" and its condition remains "Not Rated", the structure plays a significant role in managing water resources in the area. With a maximum storage capacity of 45.49 acre-feet and a surface area of 2.71 acres, Gilliam Dam provides essential water storage and flood control functions. Despite the lack of detailed information on its risk assessment and emergency preparedness measures, the dam continues to serve as a key component of the local water management infrastructure.
As a water resource and climate enthusiast, understanding the details and significance of Gilliam Dam can offer valuable insights into the management of water resources in the region. While more information is needed to assess its overall condition and risk management strategies, the dam's presence and operational status underscore the importance of maintaining and monitoring such critical infrastructure in the face of changing climatic conditions and water resource demands.

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 Gilliam Dam
Where does the data for Gilliam 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.
