Greene County Sheriff's Office Press Release
Twin Lakes Dam Update as of 02/06/13 4:30 p.m.
All entities are coordinating efforts at this time to resolve the issue within Twin Lakes Subdivision. The issue at hand is a partial "buckling" of a section of the outlet pipe and minor separation at its joint which is causing erosion in the area.
The Twin Lakes Home Owner's Association has been instructed by an engineer and Virginia Dam Safety personnel to lower the lake level a minimum of 10ft immediately. Lowering the level will take the pressure off of the pipe as well as provide flood protection.
A CodeRED Emergency Notification was sent to all Twin Lakes residents on the evening of 02/05/13 advising them of the compromised pipe/erosion issue. All residents downstream of Dam 2 and Dam 3 were advised to make preparations now in the potential event of a failure.
The Home Owner's Association is actively working on obtaining a contractor and is hopeful for a start date of February 7 or 8. The lowering of the water level will be a slow process. To avoid any slope issues inside the lake, water will be lowered at a rate of 6-12 inches per day. While officials feel the dam is structurally sound at this point, any outside influence could negatively affect the situation in a rapid manner.
The Home Owner's Association has already initiated their emergency action plan and has been actively coordinating efforts with Greene County Emergency Services personnel.
