flies for fishing August in Montana

What’s in my flybox for the Month of August?  Hoppers, ants, spruce moths, tricos and beetles.  Normally, my fly boxes are full of mainly hoppers for August fishing in Montana.  This summer, with the low clear water conditions, fish are keying in on smaller insects like tricos and other small mayflies that are prolific during the early morning hours.  I’ve seen numerous 20″ fish sipping on size 22 spinners on local freestone rivers the last couple of weeks.  Fishing micro-patterns is a common occurrence for our tailwater fisheries, but not necessarily the norm for freestone streams unless you’re willing to seek out those large sipping fish in slow, lazy shady water.  Chucking a plump hopper next to a sipping fish can sometimes draw a strike, but it’s usually better to present a small parachute fly, like a parachute adams or purple haze instead.

Ants and beetles are great searching flies for the month of August any time of day.  If nothing else is happening, try fishing one of these smaller terrestrials.  I’ve seen feeding fish, sipping on spinners, move a couple of feet to eat a black foam ant or beetle.  If in doubt, whip a black fly out.

The bulk of my August fly boxes are still filled with hoppers of every size and color.  Usually, size 10-12 hoppers are the go-to hopper size, but it pays to have a couple of huge size 2-4 hoppers to fish in deeper water, or out in the middle of the river when the fish aren’t taking hoppers along the rivers edge.  Each year, and even day-to day, the fish seem to prefer one color of hopper over another.  Currently, this year, goldenrod and tan hoppers have been the most productive colors.  Last year, pink bellied hoppers were the clear favorite.

Keep me posted on what’s in your fly box.  It’s always interesting to hear what’s working on your local streams.
