I've only paddled the Bonanza Bridge to Enron Takeout. The BLM map for this is fairly quality and adequate. http://www.blm.gov/style/medialib/bl...0for%20web.pdf
Pertaining to that section. Still some private land, however, limited mostly to ranching and grazing, and oil rigs on top of the canyon edges. Two days was good, and most wouldn't want less time. We had a full day on Saturday, and half day on Sunday. I think somewhere around 600cfs. If you are thinking rafts, you want more water, and small, lightly loaded boats. Self support kayak, canoe, and IK are much more appropriate at flows under 1000cfs. Whitewater is consistent II+ with some strainer and tree negotiating. We camped at the labeled camp sites for the Goblin City view area, which is in one of the best cottonwood groves (the bank up was ridiculously steep and muddy but once in the grove there were a few nice camps, enough space for 3-4 small groups to share). Bring the hammock. The hiking was nice, although, less spectacular than some desert areas. Random wildlife highlight was an Albino Blue Heron (didn't know they existed).
The Enron take-out road is better with high clearance vehicles, and I wouldn't want to drive it after a heavy rain storm. The takeout boat ramp wasn't very trailer friendly last spring.
I guess the real highlight of this stretch is the lack of other people. If you need something off the beaten path, as an alternative to the super busy sections of the Colorado, then the White River can make a great weekend trip.
