The Boise River (in town) is also picking up & fishing good.  We’ve got about a month or so before the flows pick up, so be sure to check out our real time streamflows.  Stop by the shop & stock up with bead head nymphs, pheasant tails, hares ears, copper johns, smaller sculpins, & leech patterns are your best bet.  You might be able to find some rising fish in the East Boise area (by hwy 21) on blue wing or midge patterns. Mainly they are still sub-surface.
