no you can not. there are rapids below Barker that sometime you cant even get a canoe thru when the water is low
I don't see any Dams on the map, might have to call a place or someone up in that area to find out.
Don't think or recall that you can, but don't take my words for it. Haven't fished it in many moons. Sure a map(s) would be able to tell though.
Can you get through to the main part of the Chippewa flowage from Barker lake by boat?
