Joseph Creek, Powder River

I am just curious if anybody out there has attempted to hike into and fish Joseph Creek in Northeast Oregon? I made two trips into there this spring and haven't quite found what I was looking for yet. I would be interested to know about anyone else's experience there. For mine you can read my two trip reports at http://www.hiddenpools.blogspot.com/

Also has anyone floated the Powder River below Thief Valley Reservoir when the water was at normal flows? I am curious how much work it would be. I floated it last weekend, but the water was high. I have a trip report posted on the blog as well. I would be curious to know how long a float would take at normal water levels and again how much work it would be.
