Storm Damage Across DMV

Due to the heavy rains from Hurricane Irene, St. Mary's County issued a potential St. Mary's Lake Dam failure notification.

Irene had poured more than 7 inches of rain in the area by the time the Code Red notification at 10:40 p.m. People who live downstream from the dam are threatened by the possibility of significant flooding.

“The dam itself at St. Mary’s River Park is holding well,” said Christy Bright. “There is no imminent danger or possible danger with the dam itself. What is happening is that the level of the lake is rising, which is going to cause water to enter a spillway, which is a proactive measure to safeguard the residents from the dam and also keep the potential weight off the dam."

There is still a long way to go before the water crests and goes over the spillway. In that event, 28 residents could be affected. Those that can evacuate should. Those that can’t should go to an upper level of their homes.

They are advised to take the following precautions:

  • Move family and pets upstairs or to a high place with a means of escape.
  • Turn off gas, electricity and water supplies if flood water is about to enter your home and it is safe to do so. DO NOT touch sources of electricity when standing in flood water.
  • Keep listening to local radio for updates.
  • Flood water can rise quickly. Stay calm and reassure those around you.
  • Avoid walking through flood water.
  • Keep children, pets and vulnerable people away from flood water.
  • Wash your hands thoroughly if you touch flood water.
  • Do not drive through flood water. About 60 percent of all flood deaths are people in vehicles that are swept away by moving water.
