The Lewis River is a significant waterway in southwest Washington, originating in the Cascade Range and flowing westward to join the Columbia River. This 95-mile river system consists of two main forks - the North Fork and the East Fork - which converge near the town of Woodland before continuing as the mainstem Lewis River.

The North Fork Lewis offers diverse paddling opportunities, from placid flatwater sections to challenging whitewater. The upper reaches feature Class III-IV rapids through a narrow canyon, including the notable Gunsight rapid with its 4-foot ledge drop. Downstream, three reservoirs - Swift, Yale, and Merwin - provide calm waters for flatwater paddling and fishing.

The East Fork Lewis River is renowned for its whitewater, particularly the 3-mile Middle Section from Sunset Falls to Horseshoe Falls. This Class III-IV run is a Pacific Northwest classic, featuring scenic waterfalls and challenging rapids like Sky Pilot, Screaming Left, and Dragon's Back. The pool-drop nature makes it suitable for intermediate paddlers at lower flows, while high water significantly increases difficulty.

For a more leisurely experience, the Lewis River-Vancouver Lake Water Trail offers 32 miles of scenic paddling. This route connects Vancouver Lake, Lake River, and the North Fork Lewis River, passing through wildlife refuges, state parks, and diverse ecosystems.

The Lewis River's flow peaks in late spring with snowmelt, offering optimal whitewater conditions. Summer and early fall provide more stable, lower flows ideal for less experienced paddlers. Winter rains can create high, challenging conditions for experts.

Wildlife enthusiasts may spot bald eagles, ospreys, and various salmon species. The river corridor supports diverse flora, including Douglas fir, western red cedar, and big-leaf maple.

Key access points include Sunset Falls Recreation Site on the East Fork, and various put-ins along the North Fork, with the towns of Woodland and La Center serving as nearby hubs. Paradise Point State Park offers camping for multi-day trips.

Paddlers should be aware of woody debris, particularly on the upper sections, and cold water temperatures year-round. Some sections require portages around unrunnable falls or dam structures.

The Lewis River holds cultural significance for local Native American tribes and played a role in the region's logging history. Today, it serves as a vital resource for hydroelectric power, recreation, and wildlife habitat.
