Lower Baker Dam (or simply Baker Dam) is a dam across the Baker River one mile north of Concrete, Washington. It forms a reservoir called Lake Shannon which stretches {{convert|7.5|mi|km}} upstream. The dam is operated by Puget Sound Energy as part of the Baker River Hydroelectric Project.{{cite web

The dam has a thick arch design, and is {{convert|285|ft|m}} high and {{convert|550|ft|m}} long. It spans the Baker River in a narrow reach known as Eden Canyon, just above the river's confluence with the Skagit River. It is able to hold {{convert|161470|acre.ft|m3}} of water, of which {{convert|29426|acre feet|m3}} is reserved for flood control. At full capacity the dam's hydroelectric plant can generate 79 megawatts of power.
