Main Stem Snake River, September 29th, 2020

With flow reduced to normal seasonal amounts, now is the time to walk-in or boat fish the river almost anywhere from Menan to American Falls Reservoir.  It  offers a less crowded alternate to the South Fork and lower Henry’s Fork. Brown trout are starting to migrate to spawning areas, so under low light conditions streamer fishing will be the best way to encounter them. Midge and BWO hatches will provide top water fishing in some locations.  Remember that the river is big and powerful, so wade carefully and do the same if boat fishing ( know where diversions are) is your way to fish.

Flow is a bit below seasonal normal throughout the river, and brown trout are chasing streamers from Menan to American Falls Reservoir.  Evenings and early mornings are best time to encounter these browns. The river below American Falls Dam is flowing a measly 400 cfs. That concentrates fish, and presenting streamers can be productive. Beware of weekend crowds.

Flow throughout the river is at seasonal normal or slightly lower. There are numerous walk-in wade locations  from Menan downstream to American Falls reservoir. The same applies to float fishing.  We can help pinpoint the best locations for either way of fishing.  The river below American Falls Dam is at it seasonal low, around 450 cfs, and offers the same ways of fishing. Shorelines there get particularly crowded  during weekends. Up and down the river streamer fishing is the “name of the game.”

Flows are dropping making either walk-in wade or fishing through boating practical.  Migrating browns are the big attraction and respond to well placed streamer patterns whether presented through boating or wading. Consider that there are more brown trout in the main stem from American Falls Reservoir upstream than in the South Fork and the lower Henry’s Fork.

With less irrigation water in demand meaning reduced flow in the Snake River, it is time to have streamer patterns ready for migrating browns as well as big resident rainbows.  Drift boating is the best way to encounter these, but there are walk-in wade locations along the river. Get in touch because we can pinpoint these for you.

For the river above American Falls Reservoir all gage readings show flows about 50% higher than normal. Look for these to stay high with flow out of Palisades Dam on the increase. Flow below the reservoir is about 6700 cfs ( Anchors away, my friend!) whereas normal is around 2700 cfs.

With water storage season beginning, flow in the Snake River is dropping ( 3510 cfs at Eagle Rock, 3790 cfs at Shelley, 3620 cfs     at Blackfoot).  With brown trout in their annual spawning migration,  streamer presentation is the name of the game on the river.  Doing so under low light conditions will be most effective to maybe encounter your biggest trout of the year.  Float fishing is the best way to fish, but there are plenty of good walk-in wade locations. We can point out many of these to you, so get in touch, or visit the shop.
