Green and grey drakes, flavs and PMDs are coming out on the lower river, fish are hitting these very well, and word is out. This shifts fly-fishers from the upper river as well as bringing in those in waiting. So both places are well attended. Looking for a Henry’s Fork location with fewer fly-fishing attendees but with good fishing? Try the river in the Nature Conservancy’s Flat Ranch. It’s really the Henry’s Fork according to the USGS even though the rest of us call it Henry’s Lake Outlet.
