Wynoochee River Fishing Report: Steelhead and Salmon Runs

The Wynoochee River is a pristine tributary of the Chehalis River located in Grays Harbor County on the Olympic Peninsula. Known for its steady flows regulated by the Wynoochee Dam, this river offers excellent opportunities for anglers, particularly those chasing winter steelhead. Checking the latest Washington river flow data is always recommended before your trip, as dam operations can affect river levels.

River History and Flow Control

The flow of the Wynoochee River is largely controlled by the **Wynoochee Dam**, a project completed in 1972 primarily for flood control, water storage, and low-flow augmentation. The dam creates Wynoochee Lake, which serves as a reservoir and profoundly stabilizes the downstream flow. Because the dam acts as a barrier, all salmon and steelhead accessing the Wynoochee are either trapped at the lower fish trap and transported upstream, or are focused on the river sections below the dam.

The stable, cool-water environment created by the dam’s operation helps maintain a predictable habitat, making the Wynoochee a reliable fishery, even during dry periods when other rivers may be too low to fish.

Location and Access

The Wynoochee River flows through dense forestland before meeting the Chehalis River near Montesano. Access is primarily found in the lower river sections and along the access road leading toward the dam, particularly around the Wynoochee Fish Hatchery and public parks near the confluence with the Chehalis. Its remote, scenic setting offers a wilder fishing experience compared to urban Puget Sound rivers.

Primary Species and Seasonal Runs (Salmon & Steelhead)

The Wynoochee River is one of the premier steelhead destinations in the Chehalis basin, supported by the local hatchery. While it sees runs of salmon, it is the pursuit of the winter steelhead that draws most anglers to its clear, cold waters.

Fish Run Timing:

• Coho Salmon: The Coho run is strong and begins in earnest in late September, peaking throughout October and November. Many fish utilize the lower river before being trapped at the hatchery weir.
• Chum Salmon: A substantial Chum run enters the lower river in October and continues through December. This run provides a late-season opportunity for anglers utilizing heavy gear.
• Fall Chinook Salmon: While present, the Chinook run is smaller and typically targeted in the lower reaches near the Chehalis confluence during September.
• Winter Steelhead: The primary species and most reliable fishery. The run begins in late November and peaks sharply throughout January, February, and March. Steelhead fishing is excellent throughout the middle and upper river sections below the dam.

Regulations and Conservation

Regulations on the Wynoochee are complex due to the presence of the fish trap, wild steelhead conservation zones, and tribal co-management. Specific rules often dictate whether the river is open, where fish may be retained (if at all), and whether certain areas near the dam or hatchery are open.

Always check for emergency rule changes regarding fishing areas, gear, and limits before visiting the Wynoochee River. For the most current rules, seasons, and any emergency closures, always check the official resources from the Washington Department of Fish and Wildlife (WDFW).
