With summer heat on us, it is time to leave fly fishing on the Firehole River until the fall BWO season. It looks like Fall River Basin run-off has peaked.  So, Bechler and Fall River and Boundary Creek are now in fishing condition. Some run-off remains in each, and water is a bit cool for aquatic insect activity. Thus best approach is to present San Juan worm variations, big woolly buggers and streamer patterns of choice.  Expect standing water in any meadow areas, as well as mosquito populations building to huge concentrations.  If you can get a floatation device into Shoshone Lake and have leech and streamer patterns to present on a full sink line, you will really enjoy fishing for juvenile lake trout. Shoshone Lake is the easiest to reach if the fly fisher does not mind packing a flotation device and relevant gear three miles down the Delacey Creek trail to the lake. Get out on the lake, look for submerged weed beds. Present any fly that simulates a leech or a streamer patterns using a full sink line and stout leader.
