Sasquatch,
Just wanted to mension a few other places for lodgeing over in the kettle creek valley for you. www.kettlecreeklodge.com, www.paisnet.com, www.wagonwheelcabins.com. There are also cabins in Cross Forks next to the post office and a few up on the hill behind Kinney's store. Not sure how to contact those two. Just from being up there for years alot of these place are rented out a year in advance for the following April weeks. I also have a camp down from Cross Forks and I can sleep 3 + myself.
Just my thoughts on an April jam up there. April is pretty unperdictable at that time of the year with the weather and the water flows. As far as the crowds, the bigger waters are still crowded but the tribs see hardly any pressure at all. And as for the hatches you might catch the tail end of the Hendricksons and you should hit some Quill Gordons if the weather is decent. As you probably know the weather is a little different up there. Chances are real good it will be ugly.
Just my thoughts again. Late September is a great time to be up there. Weather will be cool and a little more predictable the streams have a decent flow and the tribs will fish great. But the non approved trout waters will be off limits. But I don't think that would matter there's lots of good approved water everwhere still holding fish. As for the crowds there's no one fishing. And as far as the hatches go you have BWO's, Slate Drakes, and Tan Caddis's.Beetles, Ants and Hoppers are still working yet.
But anyway I'll go along with what ever month. I'd just like to attened this jam. I'll be able to show some of the other guys around on some of the streams. If there's anyway I can help you out with jam let me know.
