Everyone knows the giant and golden stonefly hatches are making for good fishing from just above Chester to Box Canyon. So the river here is crowded with boating and wading anglers. In several days these events will be over, but give the fish time to digest their bugs, and they will be looking for more. Figure on about a week for fish in a given location on the river to respond again to dry patterns. But weather and flow conditions can alter this time span. We have reports that there are trout in the river in the Nature Conservancy’s Flat Ranch Preserve, but not a lot. These are mostly escapees from Henry’s Lake and they will likely take patterns that work in the lake until aquatic and terrestrial insects begin emerging in good numbers..
