About this dam

Billy Alverson Dam

Billy Alverson Dam, located in Eden, North Carolina, is a privately owned structure designed by USDA NRCS for recreational purposes, specifically Fish and Wildlife Pond and Recreation. Completed in 1983, the earthen dam stands at 30 feet tall and spans 401 feet in length, with a storage capacity of 29 acre-feet. The dam overlooks Tr- Hogans Creek and is managed by the Natural Resources Conservation Service.

Despite its low hazard potential and moderate risk assessment rating, the condition assessment for Billy Alverson Dam is currently marked as "Not Available." The dam features an uncontrolled spillway and outlet gates, with a drainage area of 0.05 square miles and a maximum discharge capacity of 206 cubic feet per second. While the structure has not been modified in recent years and lacks inspection data, its risk management measures and emergency action plan status are also not reported.

Water resource and climate enthusiasts may find the data on Billy Alverson Dam intriguing, as it offers a glimpse into the engineering and management of a recreational water structure in North Carolina. With its scenic location and focus on fish and wildlife conservation, the dam serves as an important resource for both the local community and the surrounding environment. Further monitoring and assessment of its condition and risk factors could provide valuable insights for future conservation efforts and dam safety protocols.

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 Billy Alverson Dam

Where does the data for Billy Alverson 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 Low 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.
