Salmon & Steelhead Recovery Tracker

Cascades Eastern Slope (Major Population Group)

The Cascades Eastern Slope Tributaries MPG includes three extant steelhead populations in Oregon (Deschutes River Eastside, Deschutes River Westside, and Fifteenmile Creek) and two in Washington (Klickitat River and Rock Creek). There are also two extirpated populations; Crooked River in Oregon and White Salmon River in Washington. This MPG has a geographically complex range, embracing one major river system, the Deschutes, and several smaller subbasins on both sides of the river. The Deschutes subbasin stretches over 27,712 km2 of land in central Oregon and covers 11 percent of Oregon’s land area. The Oregon populations within this MPG are summer run with the exception of the Fifteenmile Creek population which is designated as a winter run.
