The Snake River forms a braided, island-rich border between Oregon and Idaho on this 2014 survey, where the Boise River and Owyhee River both converge upon this primary waterway. This agricultural landscape in Malheur County is defined by an intricate network of irrigation systems, including the Owyhee Ditch, Mitchell Butte Lateral, and the North Canal, which support the farms on Lincoln Bench and Nyssa Bench. The settlement of Owyhee sits near the river junction, with the Owyhee Cem nearby, serving as a focal point for local genealogy. Downstream to the north, the town of Nyssa marks the edge of the sheet. The river's morphology is documented through numerous named islands such as Prati Island, Settlers Island, and Goose Egg Island, illustrating how the shifting channels have historically influenced property and state boundaries.
