Main Stem Snake River, November 4th, 2023

Because of the drop in water flow coming out of Palisades Dam look for main stem flows Above American Falls Reservoir to do the same. Below American Falls out-flow is down to about 250 cfs making for many walk-in wade locations. concentration of fish into deep water . Presenting streamer patterns is he name of the game.

Speaking of streamer patterns, The Fly Fish Food You Tube Web site features an array of streamer patterns second to none. These are tied using a variety of synthetic and natural materials and, combinations of each as well as tying instructions for each. Fly Fish Food’s web site also offers traditional streamer patterns if you prefer using them.

Snake River at Freeman Park

It is the the best brown trout fishery in the area right now. There are several walk-in wade locations above and below American falls Dam, and much of the river is good water for boat fishing. Within the Idaho Falls city limits such places as Freeman Park have convenient access points. Pitching streamer patterns is the name of the game through using sink tip or intermediate lines. Placing flies in the right location is more important than pattern selection.

Snake River in Twin Falls Area

Brown trout are migrating throughout the river with streamer fishing the name of the game.

One thing with which we should be concerned is the quagga mussel infestation in the river around the Twin Falls area. Methods to poison these have been applied, but total elimination success is yet to be determined. Meanwhile, the river is temporarily closed to sporting activity, and a total fish kill has happened in the infested area. Why bring this situation up here? Simply because this infestation can happen anywhere. If you have fished this part of the river, wash your belongings ( boats, clothing, gear ) that have been submerged if you intend to use such to fish anywhere above Shoshone Falls. Certainly, we do not want these critters to be discovered in our waters!

Significant reduction of flow out of Palisades Dam will soon hit the river down to American Falls Reservoir. Brown trout migration is ongoing, so lower flows coming up will mean they will be more easily approached while moving. Look for lower flows in the river below American Falls dam as the reservoir is down to 19% of capacity, and water storage must soon begin.

Flow in the entire river from the Henry’s Fork confluence downstream is near seasonal normal and will drop further. With aggressive brown trout migrating to spawning areas and the river being close by a visit is quite convenient if you enjoy fishing streamers during this activity. Doing so at icon locations such as the Green, Madison, Missouri and Beaverhead Rivers and rivers within Yellowstone Park can require considerable travel whereas locations on the Main Stem can be minutes away whether you are boating or wading. With decreasing daylight hours and increased chances for unsettled weather this time of the year, lesser travel time to it can be attractive. So consider trying this river for fall-run browns, and visit Fly Fish Food-Jimmy’s for “where, when and how” information.

Flow out of American Falls Dam is about where it should be for this time of the season ( about 11000 cfs). The river is in great shape for boat travel to enjoy large trout and smallmouth bass. The bass population is perhaps the best in this part of Idaho, and offers a considerable alternate to the great trout fishing present. Streamers and woolly bugger types are best flies, especially when fished along submerged structure.

Rising flow and discolored water are slowing fishing success in the river from the Henry’s Fork confluence down to American Falls Reservoir. Flow out of American Falls Reservoir is about 7500 cfs.

Main Stem Snake River, April 30th, 2023

From the Henry’s Fork confluence downstream flow is increasing because run-off has begun in tributaries and because of the increased flow out of Palisades Dam. The USGS maintained flow graph for the river below American Falls Reservoir looks like a step function as flow is now around 6000 cfs and and will be increasing to satisfy downstream irrigation demands. So look for better fishing days on the river as we warm to where we should for the time of the year.

Main Stem Snake River, April 11th, 2023

Flow out of American Falls dam is being increased. Now about 1700 cfs. Above the reservoir access is plentiful and flows less than normal. Fishing should improve until run-off kicks in.

Main Stem Snake River, November 21st, 2022

With low flow (about 300 cfs) and therefore several access locations, the river below American Falls Dam is likely the most convenient water to fish these days. Many still waters are now iced over and ice not only rims shorelines but drifts in other regional rivers. Presenting streamer patterns and woolly bugger types gives the best chances to encounter the large rainbow and brown trout residing in water below the dam.
