According to Madison Hoofers (and PaddleGuides website), if Merrill gauge > 10k, this reach is likely runnable. Those sites further suggest the capacity of the penstock and powerplant is only 2500 cfs, which would seem to indicate that flows in excess of that should start putting water in this reach. I have seen the river at 'fish flow' (summer trickle), and it would appear that this could certainly be boatable with much less than the 10,000 those sites suggest. To be sure, it would be more technical and there would be fewer choices of lines, but it should be boatable.
