The salmonfly hatch flashes like lightning up this river, all the way from Brown’s Bridge to Wise River and beyond. More than other streams, the Big Hole breaks the rules, with emergences popping up here and there instead of progressing upstream in orderly fashion. Visitors need to be aware that the two most popular floats, from Wise River to Divide, and from Divide to Melrose, are closed to floating by out-of-staters and guides on alternating weekend days.
