I own a Dory but thought you were just a fishing. That and I was busy messing with neocons on BT. But you can run stuff much lower than you think. Well at least I can

. Pumphouse goes at about 800, Ruby horse/theif about the same maybe lower, westwater 5ish, cat 10ish, Grand 10ish, Greenriver to the confluence 500 although I did hole it there. These are not high flows and I would guess using your Dory would be well down the list of your worries if things got to low to use said Dory. sj
