Gulkana River Fishing Guides and Conditions, Alaska

About the Gulkana River

The Gulkana drains south out of the Alaska Range into the Copper River near Glennallen, and it is one of the few genuinely wild Alaskan rivers you can reach and float without a plane. Congress designated it a National Wild and Scenic River, and the Bureau of Land Management administers the corridor, which means the banks stay undeveloped for most of its length. The classic trip puts in at Paxson Lake around milepost 175 of the Richardson Highway and takes out at Sourdough Creek near milepost 147, a multi-day float that includes a portage around Canyon Rapids. Below Sourdough the river eases and the lower float down to the highway bridge is the one most anglers do in a day.

King salmon are the headline. They enter in June and the run holds through July, and because the Gulkana is one of the most accessible king fisheries in the Copper drainage it draws serious pressure in a good year. Sockeye follow from June into August and are the more dependable fish for most trips. Behind the salmon, and often more interesting, are the resident fish: wild rainbow trout that feed on drifting eggs through the spawn, and arctic grayling that are here from ice-out in May until the river shuts down in September. The Gulkana is one of the better roadside grayling rivers in the state and they will take a dry fly all summer.

Openings on this river move. Alaska manages king salmon on the Copper drainage tightly and issues emergency orders in season that can close, shorten or restrict a fishery on short notice, so the printed regulation summary is a starting point rather than an answer. Check the current emergency orders before travelling. Conditions matter as much as regulation: the river runs glacial-tinged and pushy after warm weather in the range, drops and clears through August, and the Sourdough gauge reports both discharge and water temperature, which is the pair of numbers that tells you whether the salmon are moving and whether a float is comfortable.

Access

Paxson Lake BLM campground, Richardson Highway milepost 175 - the standard upper put-in for the Wild and Scenic float.
Sourdough Creek BLM campground, Richardson Highway milepost 147.5 - take-out for the upper float and put-in for the lower.
Poplar Grove, Richardson Highway milepost 136.4 - trail access to the lower river.
Sailors Pit, Richardson Highway milepost 129.3 - lower-river access and a common bank-fishing stop.
Gulkana river access at the Richardson Highway bridge, milepost 126.9 - the lowest take-out, near Gulkana and Glennallen.
141 Mile Trail, Richardson Highway around milepost 141 - foot access between the two campgrounds.
USGS 15200280 at Sourdough sits mid-river and reports discharge, stage and water temperature.

Seasons

Spring: ice goes out in May and grayling fishing starts almost immediately, often the least crowded and most pleasant fishing of the year. The river is high with snowmelt.
Summer: kings from June through July, sockeye June into August, and grayling throughout. This is the busy season and the one governed most tightly by emergency orders.
Fall: September brings the best of the rainbow fishing as fish key on salmon eggs, with grayling still active and almost nobody on the river.
Winter: over. The fishery effectively closes with freeze-up in late September or October and the corridor is not fished again until spring.
