In March 2006, CREST completed an update of the Wahkiakum County Shoreline Atlas. The project was supported by a grant from the Washington State Department of Ecology. Funds provided were federal Coastal Zone Management 306 funds (National Oceanic and Atmospheric Administration, Department of Commerce).

The table below contains downloadable versions of atlas maps. The files are in Adobe Acrobat .pdf format and are relatively large (file sizes shown in parentheses).
