Lower Gulkana River

The feel

The lower Gulkana is a 32-mile section running from the BLM Sourdough campground at Mile 147.5 of the Richardson Highway downstream to the Copper River. It is generally clear, with low to medium flow, and friendly for families floating. After heavy rain the water can turn murky and hard to fish.

Most anglers float from the Sailor's pit access at mile 130 of the Richardson Highway down to the Richardson Highway Bridge, though some start at Sourdough. The area around the bridge gives good king and sockeye salmon fishing. Some anglers run jet boats 2 to 3 miles upstream from the bridge, or motor down to fish the mouth when water is high enough.

What to expect

Water and access

Foot access around the Richardson Highway bridge and on short 17B easement foot trails at mile 137 and mile 141. Floaters carry rafts to the river. Power boats launch at an undeveloped launch at the bridge and a developed launch at Sourdough Campground.

Species and timing

King salmon May 15 to July 19. Sockeye salmon June 1 to Sept 30. Arctic grayling, rainbow trout and steelhead year-round. Whitefish are also present.

Methods and gear

Rafts, floats and jet boats are all used. Power boats generally cannot run between the two launches because of high gradient river about midway.

License and rules

Special regulations apply to specific rivers and species, so carry the current regulation booklet. Glennallen Area Office: 907-822-3309.

Hazards

High gradient river about midway between Sourdough and the bridge. Murky water after heavy rain.

Season and access

Most land along the river is privately owned by area Native Villages or Corporations, and an access permit may be needed to cross it. No launch fees at either launch.

Mingo says

Fish the bridge area while the king window is open, or later for sockeye. Hold off after heavy rain, when the water goes murky.

Before you go

• Check whether you need an access permit before crossing Native Village or Corporation land.
• Pick up the current regulation booklet and check for emergency orders.
• Plan your launch: the Sourdough Campground has a developed launch and the bridge launch is undeveloped, both free.
• Call the Glennallen Area Office at 907-822-3309.
