Giant stoneflies are crawling in Box Canyon, and adults are emerging from there on down to Warm River. Current problem is the cool, rainy weather is keeping them from flying and laying eggs. You can see bugs laying low almost everywhere. When skies clear, the sun comes out, and they warm up, there will be some GREAT fishing with those big floating patterns. Don’t be concerned so much with “which pattern to use”, be more concerned with putting them in the right location such as around stream banks, overhangs, rocks, and logs. It’s been a while since nymphs have been available at locations in Cardiac Canyon (Hatchery Ford, Mesa Falls, Bear Gulch ), so when adults become active here, you will want to be at one of these whether you float through or walk in. Bring caddis life cycle patterns to these locations as fish will respond to them too. PMDs are showing in good numbers on the lower river, so add them to the BWOs, caddis and golden stones for attracting feeding trout.
