Lake Anna Dam And Reservoir - Dike Ii dam
Lake Anna Dam And Reservoir - Dike Ii
Lake Anna Dam and Reservoir - Dike II is a vital water resource structure located in Louisa, Virginia, designed by Stone & Webster Engineering Corp. Built in 1972, this earth dam stands at 23 feet high and has a storage capacity of 487,000 acre-feet, primarily serving as a water supply for the region. With a surface area of 13,000 acres, the dam plays a crucial role in ensuring water availability for the surrounding area.
Managed by the Federal Energy Regulatory Commission, Lake Anna Dam and Reservoir - Dike II has a low hazard potential and a high risk assessment rating. While it lacks certain regulatory oversight at the state level, the dam is inspected every three years to ensure its structural integrity and safety. The dam's associated structures include VA177002, VA177002S001, VA177002S003, VA177002S004, and VA177002S005, all contributing to the effective management of water resources in the region.
Located on the North Anna River within the Baltimore District, Lake Anna Dam and Reservoir - Dike II is a significant infrastructure for water storage and supply. With its strategic design and purpose, the dam serves as a critical component of the area's water management system, highlighting the importance of sustainable water resource practices in the face of climate change and increasing water 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 Lake Anna Dam And Reservoir - Dike Ii
Where does the data for Lake Anna Dam And Reservoir - Dike Ii 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.
