Lake Barcroft Dam Information


Lake Barcroft imageThe City experienced extensive flooding in June 2006.  The cause of the flooding was thought to be the Lake Barcroft Dam.  The City initiated a study conducted by the Army Corps of Engineers which concluded that the Dam did not contribute to the flooding. 

After the incident the City worked closely with the lake Barcroft Dam owners to improve coordination and emergency planning in case of a Dam incident.  This resulted in an automated notification system and back up generators to power the Dam controls.

Last year the Virginia Department of Conservation and Recreation (DCR) imposed new requirements on Dam operators that required additional emergency planning and study of the Dams.  The Lake Barcroft Dam owners hired a consulting engineering firm which developed emergency plans for the Dam and coordination plans with Fairfax County and the City of Alexandria.  These plans are currently being reviewed by the DCR and are not publicly available.

After receiving the study the City of Alexandria reached out to several community groups and provided the information in the power point presentation below:

Since that time the City has received additional data and created draft emergency plans for the possibility of a Dam failure.  The City of Alexandria will be holding a public meeting on June 24, 2009 at William Ramsey Elementary school beginning at 6:30 p.m. to discuss our planning efforts and provide data to residents in the area potentially affected by a dam failure.
