The big bugs are out and flying all along the lower river. This will make for crowds being present to enjoy responding fish. Bear Gulch is one of the best locations for finding solitude during this event, and the big stonefly hatch here is as thick as any location on the river. Most boating anglers will be on the river below (hard bottomed boats are not allowed to portage down the slide below Lower Mesa Falls Campground), and few anglers are willing to walk the near-mile downhill to the river at the Gulch. Certainly with the warming weather coming up the hatch will advance quickly up the river. So such as Mesa Falls, Hatchery Ford, and Riverside will be locations to consider soon for meeting the hatch.
