I've never been down the Rogue with less than 1500 CFS so can't comment on that. The ladder will probably need help from the shore as previous people have mentioned. But should be doable to get down, if a little slow perhaps.
One note on the middle chute: I've run it in a 14' at 1600CFS and in inflatables, but also have seen a 16' get stuck in there at 1600CFS, and that wasn't a pretty site. As one who has also swum the eddy at the bottom of that chute (this month in fact
) avoid that if at all possible. Very strong eddy with potential to pin you under as well as wash you on the rocks all day long. If you are gonna take the middle, consider the width of your boat, and stay IN the boat if at all possible.
As far as entering the chute, it is not too difficult IMO, just scout your line if you're not familiar with it (not a bad idea even if you are familiar as it is an easy scout).
Good luck on your run!
