About this map

The Owyhee River converges with the Snake River along the border of Oregon and Idaho, defining a landscape of complex irrigation and river islands. The community of Owyhee and the Owyhee Cem sit at the heart of this agricultural region, where the Owyhee Ditch and the Mitchell Butte Lateral demonstrate the extensive water management required for farming the Lincoln Bench and Nyssa Bench.

Downstream from the city of Nyssa, the river environment is characterized by numerous named islands, including Settlers Island, Big Cottonwood Island, and Billy Goat Island. The intricate network of drainage features like Kingman Drain and Akali Drain illustrates the high-intensity cultivation of the valley floor. This map captures the intersection of natural river morphology and the human-engineered water systems that sustain the local economy.
