Lower Madison River Fly Fishing in August
Early morning hopper fishing in August brings some large Madison River brown trout to the net every year. Afternoon fishing closures are in place through August 15 on this stretch of river. Conditions typically improve with longer nights and the region’s first cold front, sometime in late August.
Relatively light fishing pressure throughout July and early August creates excellent fishing opportunities for the advanced angler between Warm Springs and Greycliffs Fishing Access Sites.
Lower Madison River Fly Fishing Hacthes in August
Terrestrials like hoppers, ants, and beetles are good bets on the Lower Madison River in August. Tricos and black flies hatch consistently in late August, and Lower Madison trout key into the nymph and pupa stages of these insects.
August Fly Fishing Techniques on the Lower Madison River
Nymphing with tandem rigs is most productive. We recommend a lightly weighted crayfish imitation followed by a small, black nymph like a Zebra Midge.
Terrestrial dry flies with weighted nymph droppers will also attract trout on sunny days throughout the month.
Aquatic vegetation growth can be problematic for less experienced anglers during the summer months; this starts to abate in late August.
Bozeman Fly Fishing Guide Pro-Tip:
If the vegetation is becoming too frustrating, try using barbless Perdigon-style nymphs. These patterns have UV resin bodies that shed unwanted debris easily. Tying your flies to a thinner diameter tippet 4.5-5.5x will help slice through weeds as well.
