About this map

Malheur Butte stands as a prominent volcanic landmark overlooking an intricate network of irrigation and drainage systems crucial to the agriculture of Malheur County. This 2017 survey details the complex water management infrastructure that has shaped the region, including the Owyhee Canal, the Malheur Siphon, and the Brosnan Ditch. These man-made channels cut through the dry terrain, feeding the valley between Alkali Gulch and the Malheur River.

The landscape transitions from the residential development of Ontario and Ontario Heights to the rugged draws of Jacobsen Gulch and Coyote Gulch. Modern infrastructure is evidenced by the Ontario Municipal Airport and a grid of roads such as Heinz Blvd and Stanton Blvd, while natural water sources like Butterfield Springs remain vital features. This map documents a high-desert environment defined by the convergence of river life and industrial-scale irrigation.
