I replied on another site with this
*cut and paste*
99% of the river upstream from the Morris Valley Rd Bridge is canyon water with deep pools and runs. If the fish are in, each pool will have Coho in it from about now till March.
Most of the canyon is inaccessable unless you bushwack and then descend with ropes.
I've tubed the entire river from the bridge below the lake all the way to the bridge at Morris Valley Road.
It was a 10 hour tubing trip.
Both times were in early August. I looked into the water in many pools and runs and counted numerous Summer Run Steelies. As we got towards the end, there were several pools filled with Summer Red Chinook. One pool over 30 feet deep we counted over 70 Chinook alone.
I've thought about tubing the river and bringing fishing gear, but its pretty unrealistic. A few kms above the Statlu Creek confluence is an impassible waterfall that must be hiked around. This hike took about 40 minutes with our tubes.
The second time we tubed, we walked down Statlu Creek and tubed about 10 kms to Morris Valley Rd. There are actually more fish in this bottom half of the river then the upper 10kms...or at least going by my counts. This trip only took 5 hours to tube.
Just a word of caution. There are some beautiful pools directly above and below the Statlu Creek confluence, but once you go down the creek you CANNOT get back up. Towards the bottom of Statlu Creek, you must float from wall to wall in a canyon that has a 30 foot + deep pool. Its easy to get down, but you'll never get back up...if there is any current at all. I suppose super low water it might be possible.
Anyways....the rest of the pools below Statlu Creek would require bushwacking and/or ropes to get into.
There are a couple of secret spots that guys go into, where there is 'reasonable' access, but good luck finding someone to tell you where they are. You can go up the west side too, and there is a logging road that will bring you close to a few spots as well.
