Largemouth Bass

Largemouth Bass fishing near Castle Rock, Washington, centers around the Cowlitz River and its associated lakes and sloughs. Silver Lake is a popular choice, known for its healthy bass population and diverse habitat. The best time to target bass here is during the spring and fall. During the spring spawn, focus on shallow, protected areas with vegetation or submerged structure. In the fall, bass will be actively feeding to prepare for winter. A good local tip is to explore the backwater sloughs off the Cowlitz River; these areas often hold good numbers of bass and receive less fishing pressure. Be aware of fluctuating water levels in the Cowlitz due to dam operations. The bass in this area tend to be opportunistic feeders, so a variety of lures, including crankbaits, spinnerbaits, and soft plastics, can be effective.
