Just ran it last week. Our last campsite was a flat silt bench on river right a short distance below Clearwater canyon, and maybe 6 miles above Dark Canyon. At our flows, it was about a 2 foot vertical drop off from the bench to the water, so we had to lift things up off the boats a little to get onto the bench. But it was a large, dry and nice camp by reservoir standards. There are also good camps upstream in the Gypsum area on both sides of the river. We motored out from Clearwater the next day, so I didn't really pay attention to camps below this. Dark canyon at the mouth was an uncampable mudpit, and the tammys at Mille Craig were underwater, so I suspect its slim pickings.
Have a great trip!
