Minister for Water Supply (Western Australia)

Minister for Water is a position in the government of Western Australia, currently held by Dave Kelly of the Labor Party. The position was first created in 1913, for the government of John Scaddan, and has existed in almost every government since then. The minister is responsible for the state government's Department of Water, which manage water resources in Western Australia. Until the 1930s, the responsibilities now held by the Minister for Water were often shared by two ministers, each with a different title.
