Just did that same float a couple of weeks ago. Only in 3 days (4 days would be better). The last camp sites are about 11 miles upstream from the Clarno takeout. For the last 10 miles, the river gets pretty lazy and (as most rivers)the wind can get bad in the afternoons. We pushed off a little before 9AM and were able to get to the takeout before noon with some steady rowing. Beware that the ramp at Clarno is very small and tends to get very congested because of the boaters putting in for the longer Clarno to Cottonwood run. Overall, it's a very pretty and relaxing float.
