Ikes section of the Klamath (lower part) has good size water in June- early July. Warning don't attempt Dragons tooth (Happy Camp run) at low water. The main Eel Dos Rios to Fort Steward or alder point is fun but the put in is awful you have to carry your stuff down nasty, horrible with a big boat, there might be other sections I haven't run do it earlier in the year about 10K-25 or so. The old put in was destroyed and it is hard to find the existing one. Eel landslides so much it changes every year, at higher flows there were definitely some class IVs. The take out wasn't too great either we backed a 4wd pick-up down to it and drove stuff up one pieces at a time I think that was Alder Point Ft Seward is easier. You have great suggestions from everyone and you have years of trips to plan.
