About Lake Merwin
Set in Washington, United States, Lake Merwin is a reservoir that holds the typical mix of warm-water and cool-water species you'd expect for the area. Anglers fishing Lake Merwin usually focus their effort on transitions: the edges of weed beds, points that stick out into deeper water, and the shaded sides of any inflow. Early morning and the last hour of light tend to be the most productive windows on a body of water this size.

Fishing Techniques
- For Kokanee salmon
Use a dodger ahead of your lure to add flash and vibration, attracting kokanee from a distance.
- For Northern pikeminnow
Focus on areas with structure like submerged trees or rock piles, as Northern pikeminnow often ambush prey from these locations; vary your retrieve until you find what triggers a strike.
- For Rainbow trout
Vary your retrieve speed when using spinners to find what triggers a strike; sometimes a slow, steady retrieve works best, while other times a faster, erratic retrieve is more effective.
