During the early 1970s, the construction of State Highway 20, crossing the Swinomish Channel to Fidalgo Island, was built through a portion of Telegraph Slough. This created a shorter inter-tidal slough on the north side of the highway, and a freshwater wetland on the south side. DNR owns the 30-acre isolated wetland and a land use agreement with them allows WDFW to manage it for waterfowl hunting and wildlife observation. A parking area on the south side of Highway 20 provides access.
