Before the motor rules changed on these two rivers, they were an excellent place to get late chrome. The rules are 25hp or less from 101 down. That eliminated almost all boat traffic on the lower Elk. The last takeout is at 101 and the best water is belwow that. Yes there are lots of excellent holes above, but 50 drift boats a day pretty much packs all of them. I used to fish the lower Elk in my sled and have 30+ fish days backbouncing and bobber fishing. The locals put a hault to that with the new motor restrictions.
It is almost impossible to get back to the ramp with a 25hp, due to the shallow waters. When we fished it, you might see 1 or two other boats. You could use a drift boat, but your takeout is the ocean and it is not a place to be at high tide. It really is not an option now. Seems like more and more places are losing water for motor boats all the time. Funny how Oregon had three times as many lisenced motor boats yet, very limited areas to use them.
