The run from the locked Weyhauser gate to the main road is 7.5 miles. The river is a wood collector yet boaters live along the river and frequently cut spaces for boats to pass. On 3/30/19 at a low flow of 7.7 feet, there was only one riverwide log that gave us trouble. As to rapid names, we call the rapid, approximately 1.5 miles down, Busy Town. It is a longish pooldrop/boulder garden. just over 2 miles below this is the Cable Drop (corner with gradient loss) ending in a pool. 1/8 mile below this drop is LogJam. Wood shifts so always scout! It is a logjam that you can often run to the Right however sometime there is wood blocking the right channel. The last named rapid is about a mile from the take out and is a riverwide ledge that ends in waves and holes....The run is best at about 9 feet and 7.7 feet is a slow, long paddle.

The gauge range for too high and too low is inaccurate. I ran it @ 9.75 feet and it was VERY high... So I would imagine that anything from 5.5 and above would be plenty FYI. And road access into The St. Helens Tree Farm (Weyhauser) is locked so you can only drive to 7.5 miles above the put-in bridge.

It is worth noting that the people living on this river have had problems with the public in the past, and they are very suspicious of people. As a result, you will see a lot of accesses with "keep out" signs, and you may even get a visit from a local if they see you scouting a potential takeout. However, the people in the area don't seem to have any problems with boaters - we found them to be very friendly when they found out we were not fishermen.
