Well Number 5

About

Well Number 5, also called 164th Street Artesian Well, is an artesian well in North Lynnwood, Washington at Swamp Creek. The well puts out between 10–50 US gallons (38–189 L; 8.3–41.6 imp gal) per minute.

It is one of ten artesian wells that originally supplied the Alderwood area in the 1950s. The other nine were capped when the water district contracted with the city of Everett for its supply. Well Number 5, originally drilled with a 12-inch (300 mm) pipe to 438 feet (134 m) and backfilled, taps the Intercity Aquifer between 100–200 feet (30–61 m) below the surface. In 1999, the well's "secret" location was revealed in connection with public planning related to unrelated city development, upsetting some people, and in the early 2000s, when the well's taps were moved c. 100 feet (30 m) from a wooded area beside Swamp Creek to a more visible structure alongside 164th Street, the upgraded accessibility again met resistance from some people.
