The Yakima River Delta is an area of land in Richland, Washington where the Yakima River enters the Columbia River at River Mile 335.[1] It hosts several protected areas and is crossed by State Route 240. This area is mostly floodplain with riparian-type growth, including non-native species such as Russian olive.[2] Amon Creek enters the Yakima River in this area.

The area is used extensively for recreational purposes, such as kayaking and hiking. The Sacagawea Heritage Trail, a bike path traveling through all three cities in the Tri-Cities, crosses the delta alongside State Route 240.[3]

The delta is generally bounded by Columbia Park Trail to the south and Interstate 182 to the north. A small portion of extends to the north of I-182 between Queensgate Drive and the Bypass Highway toward the site of the Duportail Bridge.[1] The portion to the east of State Route 240 is dotted by numerous islands, and Bateman Island lies immediately to the east.
