The Snake River serves as the dividing line between Oregon and Idaho in this 2017 survey, where the cities of Ontario and Payette face one another across the state border. This landscape is defined by an intricate network of irrigation and drainage infrastructure, including the Owyhee Canal, Washoe Ditch, and Brosman Ditch, which support the agricultural valley. The river itself is dotted with large landforms such as Duncan Island, Pool Island, and Welch Island. On the Oregon side, Ontario is home to the Treasure Valley Community College and several historic burial grounds like Evergreen Cem and Saint Johns Cem. Across the water in Idaho, the city of Payette sits just north of the Payette River confluence, near the Payette Municipal Airport and the smaller settlements of Fruitland and Ingard.
