Rainbow Trout

For Rainbow Trout fishing near Castle Rock, Washington, the Cowlitz River and its tributaries offer excellent opportunities. The Cowlitz is regularly stocked with hatchery trout, providing consistent action. The best times to fish are spring and fall, coinciding with stocking schedules and cooler water temperatures. Bank access is readily available along many sections of the river, and several boat launches provide access for drift boats or small watercraft. A local tip is to check the Washington Department of Fish and Wildlife stocking reports to determine when and where trout have been recently released. Standard trout fishing techniques, such as drifting bait, casting spinners, or fly fishing with nymphs and streamers, are all effective. Be aware of the river's strong currents and fluctuating water levels, especially below the dams. The Cowlitz River also supports a run of sea-run cutthroat trout, offering a unique bonus for anglers.
