East Gallatin River Fly Fishing in August
The dog days of summer hit the East Gallatin River harder than on other rivers near Bozeman. Irrigation demands draw the water levels down while returns cause much of the lower river to be very warm and off-color in August.
Heat and low water make for difficult trout fishing conditions throughout the entire East Gallatin system.
East Gallatin River Fly Fishing Hatches in August
Trico hatches stay steady through August, creating a few hours of reliable dry fly fishing near the mouth of spring creeks in the Dry Creek Road vicinity. Spruce moths can be active throughout the middle stretches, offering some dry fly fishing in the early afternoons.
In general, terrestrial fishing is sporadic on the East Gallatin River. It’s worth trying a hopper/dropper rig, however, when hatches are minimal and water conditions are good.
East Gallatin River Fly Fishing Techniques in August
Dry/dropper searching setups can sometimes be productive during the heat of summer on the East Gallatin River. Use foam hoppers with small, general nymphs tied on a 3-4-foot section of tippet.
Morning trico spinner falls become more challenging to fish with during low summer flows. Use long (12+ foot) and light (6X) leaders with sparsely tied spinner imitations, and try to make accurate, delicate presentations.
Bozeman Fly Fishing Guide Pro Tip:
Streamer fly fishing with small leech patterns on short, fast-sink tip fly lines can be extremely effective in the middle stretches of the East Gallatin River near Dry Creek Road. Try keeping your rod tip high, subtly “jigging” the fly along the bottom of faster runs and deep pools.
