The Columbia River and Snake River converge in this 2014 study of the Tri-Cities region, revealing a landscape deeply defined by water management and transportation. The meeting of these major waterways is marked by several landforms, including Clover Island, Strawberry Island, and Indian Island. The agricultural and industrial character of the area is evidenced by the complex irrigation network, featuring Columbia Canal Number 1, Columbia Canal Number 2, and Division Four Canal.
