Take that trip!
I did a drift trip down that exact stretch 4 or 5 years ago for some EPIC trout fishing. 2 of us caught around 100 fish averaging around 18"-20". Rainbows, Browns, Cutthroats & a Kokanee salmon that must have made the trek through the dam. We had a couple of fish completely school us. The Flaming Gorge/Green River is one of the coolest places I've ever been!

In the next year or 2 I'm planning on taking a week or more to drag my little alum. boat up there to work the reservoir. I know what you mean about the Lodge, those are some sick trout.
