About the yakima river


The Yakima River is a tributary of the Columbia River that flows through Washington State. It stretches for 214 miles and has a rich history, having been home to various Native American tribes for centuries. It is also a popular destination for fly-fishing enthusiasts, as it is home to a variety of fish species, including trout, salmon, and steelhead.

The river's hydrology has been impacted by human activity, including the construction of dams and reservoirs. The Yakima River Basin Storage Alliance has worked to create reservoirs and dams that provide irrigation water to farms and ranches in the region, while also helping to protect the river's ecosystem.

Some of the most notable reservoirs on the Yakima River include the Cle Elum Lake Reservoir and the Bumping Lake Reservoir. The Yakima River also supports a variety of recreational activities, including camping, hiking, and rafting.
