2024 Map of Sauvie Island
USGS Topo · Published 2024About this map
Sauvie Island dominates this landscape at the confluence of the Willamette and Columbia Rivers, defined by a complex network of sloughs, lakes, and seasonal wetlands. The internal drainage of the island is marked by Sturgeon Lake and the Gilbert River, while the western boundary is traced by the Multnomah Channel. This 2024 data reveals the persistent agricultural and conservation patterns of the island, including the Moar Cem and the extensive Ridgefield National Wildlife Refuge to the northeast.
