It's blue-winged olive time! Make sure you have plenty of Baetis nymphs! Some of my favorites include: Sparkle Wing RS 2's, Mercury Flashback Pheasant Tails, Mighty Mite Baetis, Juju Baetis, Stalcup's Baetis, Mercury Baetis, Smitty's Baetis, and Foam Wing Emergers! Trout are starting to key heavily on Baetis nymphs in the shallow riffles!
