The Yuma Water Users Association is an organization dealing with water issues in the Yuma area. It was originally organized in 1903 shortly after the Reclamation Act was passed by the United States Congress. The Association was originally created as a non- profit to represent its members in negotiations with the Bureau of Reclamation. In 1904 Congress created the Yuma Project under the Bureau of Reclamation with the intention of making the Yuma area more agriculturally profitable. Towards this end, construction was begun on Laguna Dam in 1905. Water diversion to the Yuma area was handled by Laguna Dam until 1941, when the diversion point for Yuma was switched to Imperial Dam. Through a contract with the Bureau of Reclamation in 1951, the Yuma Water Users Association assumed control of the works and facilities of the Yuma Project including both irrigation and power generating facilities. In 1962, a supplemental contract was signed giving the Association control of the Siphon Drop Power Plant and its various facilities such as transmission lines and irrigation works in California.
