The Cleveland Dam is a concrete dam at the head of the Capilano River in North Vancouver, British Columbia, Canada that holds back Capilano Lake, also known as Capilano reservoir. Part of the Capilano River Regional Park, it is not used for generating hydroelectricity, but rather for storing a portion of the Lower Mainland's drinking water. It was started in 1951 and completed in 1954, and is named after Ernest Cleveland, first chief commissioner of the Greater Vancouver Water District.
The dam is prominently featured in the Smallville episode "Leech," where Clark Kent loses his powers via a lightning strike while attempting to save a classmate from jumping from the dam. It is also featured in the second season episode of the series Supernatural, titled "Simon Said". A Cadillac goes over the dam into the Capilano River in the film The 6th Day. The dam is also a central location in the film Bad Girls from Valley High.
