2023 Map of Strait of Georgia (All Water)

About this map

Salish Sea waters define this marine quadrangle in the northwestern corner of Whatcom County, where the United States and Canadian maritime boundaries converge. This recent 2023 edition focusing on the Strait of Georgia serves as a modern hydrographic baseline, capturing the open water character of these international shipping lanes and coastal reaches. The map identifies key nautical zones including Boundary Bay in the north and the transition into Semiahmoo Bay to the east. While entirely devoid of terrestrial landmarks or settlements, the map provides precise digital-era positioning for the primary bodies of water that have historically linked the coastal communities of Washington and British Columbia.
