Lake Pateros

Lake Pateros is a reservoir on the Columbia River in the U.S. state of Washington. It was created in 1967 with the construction of Wells Dam. The reservoir lies almost entirely in Douglas and Okanogan counties, although the dam itself lies partially in the easternmost portion of Chelan County. The reservoir stretches from there upstream to the Chief Joseph Dam. Towns on Lake Pateros include Pateros and Brewster, Washington.
