I have a 17' Searay and was able to get it up there no problem. The road from Rawlins is say 40 to 50 Miles with the first 15 or so miles paved. It is a however very nice gravel road, a little steep in spots,a couple of the passes we went through on the way reached 8000', it's just a long pull.
Nice boat ramp/staging area with restroom, the only problem with the lake as I can see is that there is "No Camping" signs all over near the lake. It is out in the middle of no where, and not much access at all.
Yes please let us know how you do.
