Wauconda is a small unincorporated community in Okanogan County, Washington, United States. Once a boom town, it has dwindled almost to nothing; it is now under single ownership.Wauconda was founded in 1898 as a mining community. Three brothers from Wauconda, Illinois, discovered gold in the area and decided to name the mine after their hometown. Four mines, the Oregonian Mine and three Wauconda Mines, eventually operated in the area, quickly swelling the area's population to over 300. By 1900 the town had a general store, and by 1901 it had a post office, although the location was two miles west of the original camp. At its peak there were about 1000 residents.In the early 1900s the output of the mines declined and they were eventually closed. In 1929, the state built Highway 20 on a route that bypassed the town, so the town was relocated to be on the new road. The abandoned former town location is now a ghost town.Present-day Wauconda is much smaller than the old mining boomtown.
