About the Kobuk River
The Kobuk runs roughly 350 miles west from the southern slope of the Brooks Range, through the great sand dunes of Kobuk Valley National Park, and out to Hotham Inlet on Kotzebue Sound. The gauge sits near Kiana, a village in the lower river, well above tidewater but low enough that the river here is wide, slow and braided. This is genuinely remote Arctic country — there are no roads to the Kobuk, access is by bush plane out of Kotzebue, and the villages along the river are the only infrastructure. For anglers the Kobuk is known above all for one fish: the sheefish, an enormous predatory whitefish that the river holds in numbers found almost nowhere else, and which has made Kotzebue a destination for a very particular kind of trip.
Beyond the sheefish, the Kobuk carries a strong chum salmon run through the summer, the only Pacific salmon present in real abundance this far north. Arctic grayling are everywhere in the clearer tributaries and side channels and run to good sizes, Dolly Varden move through the system, and northern pike fill the sloughs, oxbows and lake outlets along the lower river. Lake trout and burbot hold in the deeper water and in the connected lakes, and humpback whitefish are abundant and locally important. Much of the river’s use is subsistence fishing by the villages along it, and visiting anglers should expect to be guests in a working fishery rather than on a resort river.
The gauge near Kiana reports discharge and stage but no water temperature. On a braided Arctic river the stage reading is the practical number, because it determines which channels are navigable and whether the side sloughs where pike and grayling hold are connected to the main stem. Discharge is dominated by snowmelt, so the river runs high and cold through June and settles through July and August. The fishable season is short and effectively ends with freeze-up in October.

Access
Kiana - the gauge village on the lower river and the usual access point by air from Kotzebue.
Kotzebue - the regional hub on the coast, where all travel to the Kobuk begins.
Ambler - the upriver village, the common starting point for float trips on the middle river.
Kobuk Valley National Park - the protected middle reach, including the Great Kobuk Sand Dunes.
Onion Portage - the historic caribou crossing and a well-known camp on the middle river.
Selawik River - the neighbouring Arctic drainage south, another sheefish water.
Noatak River - the large river north of the Kobuk, the obvious alternative float in the region.
Seasons
Spring: break-up and heavy snowmelt, with the river high, cold and silty and no practical fishing.
Summer: the main season, with chum salmon running, grayling in the clear tributaries and pike in the sloughs.
Fall: the best window for large fish as the water clears and cools, and the traditional time for sheefish.
Winter: iced over, with fishing limited to local subsistence jigging through the ice for sheefish and burbot.
