Dam in Greene County Damaged

Posted: Updated: Feb 6, 2013 03:02 PM EST

Some people in Greene County received a warning from the police department Tuesday night.

A code red community notification was sent out after one of the dams in the Twin Lakes subdivision was damaged.

The Greene County Sheriff's Office says a section of pipes in the dam has been affected. It's urging residents to make preparations in case the damage gets worse.

A contracting crew is expected to begin work on the dam Wednesday morning.

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. 

If anyone has any questions or concerns, they should contact the Home Owner's Association at 434-985-4450, via their email twinlakeshoa@twinlakeshoa.org or their website www.twinlakeshoa.org.  Any additional questions can be directed to the Office of Emergency Services at 434-985-8682 ext 501

Thank you
