do not take a 16 footer, it will not fit, 14 max, especially at 600 CFS.
duckies are fine, 16 footer will get stuck in at least 3 rapids, (the squeeze, feather, boulder garden?)
Good luck, lost of rock dodging but no big boat eating holes, plenty of places to ride up on flipper rocks and turn that 14 footer over,
TO THE RIVER!!!!!
