About this water

The Naknek is Bristol Bay's other great trophy-rainbow river, draining Naknek Lake past the town of King Salmon and giving the region a second river of the same calibre with a slightly more accessible, boat-and-lodge profile than the fly-out rivers. It grows enormous rainbows on the same salmon engine — smolt, eggs, flesh — and its late-season fish are the size that makes the long trip make sense. It fishes big and is best worked from a boat, with wind and weather genuine factors and bears a constant companion around the salmon. As everywhere in Alaska, the salmon runs drive the trout fishing and the regulations move with the seasons. Come for the autumn trophy-rainbow period, fish the flesh and egg patterns, and check the current ADF&G rules and orders before you book.

Under the surface

The Naknek drains the great lake of the same name in Bristol Bay country and runs short, broad and powerful to the sea, and it grows the biggest rainbow trout in Alaska — wild, lake-nourished leopard rainbows that feed on a near-endless supply of salmon eggs and flesh and reach sizes that sound like fish stories until you see one. It's a big, cold, tundra-and-spruce river over glacial gravel and cobble, fed by one of the richest sockeye systems on earth, the trout and char and grayling all riding the salmon's coattails. The flow is lake-buffered and steady; the bed is rounded gravel; the water is cold and clear-to-tinged. Wading the edges and the gravel bars is doable but the main river is big, deep and pushy, and most of it is fished from a boat. This is trophy water in the truest sense — fewer fish, but the ones that count.
