Henry's Fork River, Idaho - Fishing Report -
August 1
7, 2017
As about always, the river is in good shape and in all sections. The water levels are
a little low in places but that's fine. It just means you have to use a little caution
about spooking the trout. There are still plenty of insects hatching. Again, that's
about always the case on the river thanks to its relatively low pH.
