Beaver Lake Dam dam
Beaver Lake Dam
Beaver Lake Dam, also known as Third Branch Dam, is a gravity dam located in Chesterfield, Virginia. This state-owned structure on the Third Branch River serves primarily for recreational purposes, providing a storage capacity of 201 acre-feet. With a height of 17 feet and a length of 200 feet, the dam has a low hazard potential and is in satisfactory condition, as assessed during the latest inspection in May 2020.
Managed by the Virginia Department of Conservation and Recreation, Beaver Lake Dam is regulated, permitted, inspected, and enforced by state authorities to ensure its safety and compliance with regulations. The dam is situated within the Norfolk District of the US Army Corps of Engineers jurisdiction and is not federally owned. Despite its relatively small size, Beaver Lake Dam plays a crucial role in providing water storage and recreational opportunities for the local community.
For water resource and climate enthusiasts, Beaver Lake Dam offers a fascinating example of a state-managed gravity dam that serves multiple purposes, including recreation and water storage. With its location in a scenic area of Chesterfield, Virginia, this structure highlights the importance of proper management and maintenance to ensure the safety and sustainability of water resources in the region. The dam's low hazard potential and satisfactory condition underscore the effectiveness of regulatory oversight and inspection practices by state authorities.
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 Beaver Lake Dam
Where does the data for Beaver Lake 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.
