Henry’s Fork, June 19th, 2024

There is good reason why June could be called “the May Fly Month “ on the Henry’s Fork. Look at the roster of major June mayfly emergences up and down the river: Brown Drake, Flav, Gray Drake, Green Drake, Pink Albert, Pale Morning Dun, Speckled Dun. In addition, diminishing Blue Wing Olive mayflies, large stoneflies, and midges are present along with increasing numbers of caddis, damselflies and Isoperla stone flies. So which of these insects are trout taking at any given time? That is up to the fly fisher to determine. It is an intriguing puzzle and the main reason why this river renowned. Currently good water quality reigns in temperature and clarity throughout the upper river and on downstream at least to Chester Dam. From this location, Fall River brings in run-off water in amounts that compromise this status.
