Hey summer run, I've fished this section of the river quite a few times with my father. Yes it is possible to make it to haller, but the later in the summer it gets the harder the dift will be in a boat. There is nothing hard about the dirft, just lack of water in the late summer. And one side note Haller park boat ramp is crap. The cement ramp turns into large boulders with a steep drop off. Good luck and fishon.
