Don't want to rain on your parade but the Big Hole will likely be closed in July. It has happened almost every year we have been in Montana in July for the last 5 years. In fact this past year almost every river you mentioned was closed by mid July because of dewatering and heat. If there is a huge snow pack this year that may change so keep an eye on that. The best plan would be to plan on rivers that rarely close because they are fed by dams with cold water then change them if things are looking up for the named rivers.
