there are no more public launches in this stretch.It is of equal distance from both launches,peoria is a shallow and snaggy slew,Cartney is better launch,and the wiser choice if you are drifting.I did this stretch a few weeks ago,dont forget your trout rod.
Bangin some nice bows with panthers
+ splitshot.We did get some light bumps plunkin bait in the deep pools,but never saw a sturgy.I have heard that steelhead are taken in the riffle at irish bend,but I have never tried.
The confluence with long tom is at a side channel (fairly big side channel), see link.
long tom mouth As far as I know you can still launch at Irish Bend (no improvements, gravel), which is close to the long tom. Not much in the way of signs getting there.
