Each spring, rivers in Alaska go from ice covered to open water during a time of year we call ‘Breakup’. It is a time to be prepared. Ice jams can form during breakup and cause flooding. Join us to look at river ice and how ice jams form, and learn how we monitor breakup around Alaska. We will also find out what to expect for breakup this Spring.
