We ran the Numbers last night for a final Ark run of the season. The flows were roughly 630 when we put on and 300 when we took out. That is a very large change in volume in a channel that size. My question is what similar extreme flow changes have people experienced while on the river?
I've done Deso/Grey's when it was 5000 on day one and 15000 on day six.
I've also paddled the Middle Madawaska in Ontario where there is an agreement between the Dam/Government and the kayak school (Madawaska Kanu Centre) for releasing the water in a spurt from 9am to 3pm thus ensuring all the water is used instead of being wasted in the middle of the night. Flows will jump from about 700cfs to about 1500-2000cfs in about half an hour and will drop just as abruptly at 3:30 in the afternoon.
