Hey Jen! Welcome to the Junction! It depends on what kinda boating you do. In town, just float trip/booze cruisin' and there's a great overnite trip thru Ruby/Horsethief Canyon over into Utah, but again, flat water. Ruby ends at the Westwater put in. Westwater is a pretty epics white water daily or overnite trip. I have a friend with a permit for this weekend coming up and room on his boat if you want in. He's a good dude to know.
Other options: Plateau Creek comin' off the mesa is great for like two weeks of high run-off. Dolores and Gunni are cool too.
There's a real solid group of boaters in GJ - just kinda hard to find but I'll be happy to put you onto them
I'm more of a flat water lame duck beer drinker these days but I have plenty of crazy friends.
Let us know if you ever wanna grab a beer or hop on a float.
