Mid March -
The spring fishing on the Bitterroot and the Clark
Fork is usually the most productive. Hatches of Skwala Stoneflies
and later March Brown Mayflies can fool some of the largest trout,
particularly the hungry browns. It is a dynamic time to be on the
water as migrating waterfowl and songbirds are mating and nesting.
The river is virtually alive with the sound of birds and rising
trout. Ski/fish options are available during this season.
June 1 - July
When the rivers clear after run-off, prolific
hatches of mayflies, stoneflies, and caddis flies will characterize
this portion of the season. Hatches including salmon flies, golden
stoneflies, green drakes, pale morning duns and a host of caddis
lend variety to the angler. The midsummer season is the most
popular time on all the rivers and early booking is critical.
August 15 -
Late season fishing is characterized by the lowest
stream flows, the most particular trout and an abundance of mayfly
species that include large fall drakes, tiny Baetis and
Tricorythides. Hoppers and other terrestrials also appear in great
numbers during this time. Cool rainy weather can occasionally produce
superb fishing using dry flies and emergers, but days of Indian
summer with cold nights, warm sunny days, and golden cottonwood
leaves may be expected. This is a great time to find rising trout
and spectacular scenery in western Montana.
