You may put in at the Pleasure Park between Delta and Hotchkiss. There are several potential take outs. There are two river left maintained by the BLM and shuttled by using the bridge at Austin and then driving a couple miles on questionable roads back upriver to the ramp. You'll want high clearance to access those ramps.
Next is a private take out called Drysdale Flats. This is the best option for a daylong fishing float. Call the Pleasure Park 970 872 2525, $60 for them to shuttle. Do this in advance and expect them to maybe not have a driver available. This is what I generally do as the length is right and I often don't have a shuttle driver for a fishing float.
You'll need to run a diversion at The Orchards which is pretty easy but if you don't watch for it, it can bang up your boat a little. If you want to do a side hike, eddy out river right just after the diversion and you can hike up to an ancient archaeological dig
The next take out is at the Cedaredge bridge river left, this is the one we use when we're pleasure boating (not fishing). It's a few miles further downstream.
They've just improved the diversion just below the Cedaredge bridge so it's now runable but I haven't done it, the slot is just left of center according to the BLM. You could then take out at Escalante which would be a looooong day float and I don't know the river in that section.
You will not be able to get your drift boat under the train trestle at Dominguez. The next take out is at Whitewater which I have not used.
Good luck and feel free to PM with more questions.
