About this map

Hanford Works and its dedicated government rail line occupy the southern reach of this landscape, illustrating the significant federal footprint in the region during the late 1970s. The Columbia River serves as the central artery, controlled by the Priest Rapids Dam and the O'Sullivan Dam, which together manage the complex irrigation network of the West Canal and Potholes Canal feeding the Royal Slope. This infrastructure transformed the arid desert into a productive agricultural zone, supporting settlements like Royal City and Othello.
