Alaska Fishing by Rene Limeres and Gunnar Pedersen



Alaganik Slough beckons visitors to explore the wetlands of the Copper River Delta. A five mile road rambles through a network of ponds and sloughs. This site features a wheelchair-accessible boardwalk, restrooms, viewing shelters and picnic areas.

The slough has a big run of coho salmon and smaller runs of sockeye salmon, Dolly Varden, and cutthroat trout. Dolly Varden fishing is good in the late spring when the salmon smolts are heading out to sea.  Coho salmon fishing peaks in mid August, when the fish come from the ocean on the high tides. Early in the coho season, most of the action is in the lower slough near the end of Alaganik Slough Road. There’s a boat ramp there and also a 1/2-mile trail leading to the upstream holes. Later in the season, coho can be caught farther upstream in the holes along the Copper River Highway.

Hooligan (eulachon), a type of smelt, spawn in the slough each spring, during the highest tide cycles of the month. They’re unpredictable--but big flocks of gulls or eagles will signal that the hooligan are in.
