Conservation Story

The Lyman Slough Conservation Area can be experienced by walking the nearby Cascade Trail, which offers views of the Skagit River corridor and the surrounding landscape. A walk along the trail highlights the area’s role in supporting wildlife and river health while providing a quiet, scenic experience for visitors.

Skagit Land Trust (SLT) acquired this Conservation Area with assistance from the Washington State Salmon Recovery Funding Board, coordinated by the Skagit Watershed Council, and Skagit County Public Works to protect the significant Coho rearing habitat found at Lyman Slough.

Site History and Ecology

Lyman Slough was once a popular fishing spot on the west side of Lyman. Fishermen would walk from Lyman on the gravel bars along the banks of the Skagit River. The river is shifting, and a large slough now separates the mainland from the gravel bars for much of the year.

Large flood events in 2017 and 2025 have dramatically changed the river and the surrounding landscape. In 2018, the Army Corps of Engineers bulldozed the land adjacent to SLT’s Lyman Slough Conservation Area to install artificial erosion barriers.

The Conservation Area hosts a riparian woodland, home to many songbirds, amphibians, beavers, and bats. Volunteers have contributed a great deal of time removing invasive species and planting native species over the years.

How to Get There

Just over seven miles east of Sedro-Woolley, turn right on Lyman-Hamilton Road. Drive 1.5 miles to Lyman City Park. Park at the Lyman City Park parking area and walk toward the river to the Cascade Trail. The Lyman Slough Conservation Area is on the right along the slough.
