late season

Hello, I will be moving to Jackson Hole at the end of October from Maine and was wondering if there is any boating to be done in the general vacinity at that time of year? I dont mind of its cold but is there water?! Thanks!

I'm looking at doing a September trip through the Middle Fork and Main Salmon river. Does anyone know if it's still possible to put in at the Boundary Creek put-in at that point, or will it be too low? I've heard that put-in in September is similar to boating the Arkansas, but want to get some...
