Fly Fishing The Cowlitz River Washington
This river is full of migrating fish just about every month of the year. Its a true year-round fishery. Some months provide anglers an opportunity to catch a grand slam. It has large, Chinook salmon that will challenge anyone; sea-run cutthroat trout; summer steelhead, winter steelhead, and Coho salmon.

The river flows from glacial streams on Mount Rainier. The Cowlitz River is within a couple of hours of Seattle Washington and Portland Oregon. Although the river can get crowded in some places, it also has plenty of areas where pristine conditions exist.

Although it is know for its fine steelhead fishing, its sea-run cutthroat may be just as well liked by the local anglers. These fish average about 15 inches and large numbers can be caught at times.

Summer steelhead start coming into the river in late May. These fish average about 7 pounds. Most of the fish arrive in mid June. The fish will remain in the Cowlitz into October.

Winter steelhead start arriving in the Cowlitz River in the later part of November and the first of December. These fish can run from about 8 pound to 15 pounds. In the last part of December and January, hatchery run fish averaging about 8 pounds make their appearance.

Chinook salmon run during the Spring and again during the Fall. The Spring run starts in the middle of March and peaks in April. The average fish will weight about 20 pounds. The fish remain in the Cowlitz River until after the spawn in September.

You need a driftboat or pontoon boat to fish this river. The banks are covered with bushes and trees and there is little access. In addition to the main channel, there are smaller channels and feeder streams. There are two hatcheries on the Cowlitz River, one each for salmon and trout. The purpose it to replace those fish lost by the hydroelectric dams. Efforts are being made to reduce the population of hatchery fish while the wild fish increase.
