About this map

The Snake River forms a critical corridor along the state line between Oregon and Idaho, defining the geography of this high-desert landscape. On the western bank, the Deer Flat National Wildlife Refuge encompasses riparian habitats and river features like Porters Island and Westlake Island. The agricultural development of the area is evident through an extensive network of irrigation infrastructure, including the Galloway Canal, Grimmet Lateral, and the Domby Ditch, which channel water toward West Weiser Flat and the surrounding plains.
