Kachess River
Kachess River is a tributary of the Yakima River, in the U.S. state of Washington. From its source on Chickamin Ridge in the Alpine [Lakes Wilderness] region of the Cascade Range, the Kachess River flows south into Kachess Lake, a natural lake regulated as a reservoir by Kachess Dam. Below the dam, the Kachess River flows south and then empties into the Yakima River at Lake Easton.
