1986 Map of Sweigiler Creek

About this map

The Grays River State Fish Hatchery sits at the southern edge of this terrain, marking a point of intersection between the managed environment and the complex drainage systems of the Pacific Northwest. Surveyed in the mid-1980s, the area is defined by its deep network of waterways, including the Naselle River in the northwest and the Grays River to the south. The landscape is primarily shaped by timber and utility infrastructure, as evidenced by the Borrow Pit and a remote Radio Facility positioned on high ground. This region spans the boundary between Pacific and Wahkiakum counties, where numerous tributaries like Sweigiler Creek, Beaver Creek, and Shannon Creek converge through heavily contoured valleys. The map illustrates the specialized hydrology of the West Fork Grays River system just as contemporary conservation and hatchery management were establishing their modern footprint in these coastal mountains.
