The Branch river has a long history of being 'the river to float' for trophy rainbow trout fishing in Alaska.

It's bountiful rainbow trout kick off the season on June 8th each year as they slash into out migrating schools of salmon fry. Swinging large flies like the Dolly Lama are popular at this time!

The Alagnak's clear waters also host some of the largest runs of Pacific salmon in the world and Sockeye salmon and few jack kings arrive in the waters of the Alagnak river in late June followed soon after by the main run of adult Chinook as the calendar slips into July.

The mass influx of salmon into this uniquely Alaskan fishery does not stop there, as the sockeye and kings are closely followed by chum salmon with their runs in mid to late July headed to the lower two thirds of the river, pinks in even years and silver salmon from mid August well into September when fall fishing for rainbow trout can be hot!

Most years find us with a few trips scheduled during what we call "Sockeyefest" in late June through mid-July

While it is not just about fishing for sockeye salmon at this time, as other species abound, it is a celebration of the one fish species that drives the biological diversity of the region for if it were not for the millions of these magnificent salmon returning, spawning and then in death feeding everything here, not much, not even the beautifully spotted rainbows the Alagnak is famous for would be here!

Note: We often get requests to combine our Moraine creek float fishing trips with a segment on the Alagnak River in August and September for a true Alaskan Adventure, if that interests you, be sure to call us to check on a Moraine-Alagnak combo float fishing trip.

Our Alagnak river float trips start and end in the Alaska Peninsula town of King Salmon

King Salmon is serviced with regularly scheduled flights operated by Alaska Airlines out of Anchorage. At this time due to thier flight schedule we recommend arriving the day before your trip and overnighting so that you will be available to fly out to the Alagnak as soon as the air taxi is available the next day. It may also be necessary to overnight at the end of your trip to the Alagnak due to the scheduled time for return flights to Anchorage from King Salmon.

Upon booking, we will provide an additional trip information brochure that covers places to stay, flight information, and any new information that might not have been available when this was written.
