The water

Henrys Fork (Ashton) is a tailwater below Ashton Hydroelectric Project (FERC No. 2381) in Idaho, fished for trout, whitefish, panfish — rainbow, brown, brook, cutthroat. On dam-controlled water the generation schedule is the whole story: the wade window is the no-generation block, and rising water at the gauge means the pulse is arriving.
