Cultus Lake is a lake, associated community and provincial park in theFraser Valley region ofBritish Columbia, Canada. It is the source of theSweltzer River. Cultus Lake is located 11 kilometres (6.8 mi) south of theChilliwack River, near the city ofChilliwack and approximately 80 kilometres (50 mi) east ofVancouver.[2] In 1950, Cultus Lake became aprovincial park ofBritish Columbia. Cultus Lake covers an area of 656 hectares, evenly on either side of the lake. At one time the lake had a sawmill and booming ground until it became a provincial park in the 1950s.
Cultus Lake is an important place for spirit quests of theSto:lo people. The traditional Ts’elxwéyeqw name for the lake is Swílhcha’ meaning ‘an empty basin that quickly filled with water’ or ‘somebody died’.[3] Cultus is aChinook Jargon word meaning primarilybad,[4]worthless, orgood for nothing, though the same word can also meanfree,without purpose, or simplynothing.[5] It possibly acquired this name after the spiritual power of the lake was used up owing to its popularity.[6]

In the early 1900s, the Cultus Lake area was a popular destination, which led to the formation of a joint committee between theCity of Chilliwack and theCorporation of the Township of Chilliwhack (sic) in 1924. This then led to the formation of the Cultus Lake Park Board in 1932, which is still in effect today.[9][10] The Cultus Lake Park Board includes five commissioners, of whom 3 are elected from Cultus Lake, and 2 from theCity of Chilliwack. As of 2022, the board chairman is Kirk Dzaman.[11]
