1990 Map of Sauvie Island

About this map

Sauvie Island and its intricate network of sloughs and lakes dominate this 1990s-era landscape at the confluence of the Columbia River and Willamette River. This riverine environment is defined by expansive conservation areas, including the Sauvie Island Wildlife Area and Ridgefield National Wildlife Refuge, where tidal flats and islands like Willow Bar shift with the water. The map documents the low-lying interior hydrology of Sturgeon Lake and Gilbert River, contrasted with the industrial and transit corridor running along the western banks of the Multnomah Channel.
