We sound sirens before opening floodgates at all dams to warn people in the area. The siren sounds for 5 minutes before the first gate opens, then 1 minute before each additional gate opens. Our employees at the dams will check upstream and downstream to make sure there's nothing in harm's way before opening floodgates when possible. We also use our Flood Operations Notification Service to alert subscribers by email, text and/or phone call before a floodgate opens. Sign up here: www.lcra.org/FON
