Wells Dam
Wells Dam is a hydroelectric dam located on the Columbia River, downstream from the confluence of the Okanogan River, Methow River, and the Columbia River in Washington state. The dam, associated structures, and machinery make up the Wells Hydroelectric Project. It is owned and operated by Douglas County Public Utility District.

It has produced electricity since August 22, 1967. Its operating license from the US Federal Energy Regulatory Commission is next up for renewal in 2052. In addition to the two public utility districts, the project provides electricity to Puget Sound Energy, Portland General Electric, PacifiCorp, Avista Corporation, and the Colville Indian Tribe.

Its reservoir is named Lake Pateros. Just below and adjacent is Carpenter Island boat launch and fish hatchery river access. Lake Pateros is not deep but a high volume of water moves through it. Thus, low-head, high-volume Kaplan turbine runners drive generation.
