So, a dam is near you. Now, what?
While dams provide significant benefits, they also come with risks. Flooding can happen around and downstream of dams even when they’re working as designed.
Dams are built across rivers and hold, divert, or regulate water. Water can be held back but eventually has to be released downstream.
Heavy rains can make for larger releases of water downstream, sometimes flooding areas closest to the waterway. More dangerous flooding can happen if an issue at the dam occurs.
While we work hard to keep dams safe, partnership is key to plan ahead and work together to keep people out of harm’s way.
Flood inundation maps, like those available on the National Inventory of Dams, are a tool to help us understand flooding that could happen and design safety strategies with others.
To learn more about dams near you and possible flooding, visit the National Inventory of Dams, https://nid.sec.usace.army.mil/. You can view and find out how to contact those responsible for dams in your area.
