Mubazzarah Dam is the oldest water facility in the modern history of the Emirate of Abu Dhabi. It was built in 1955 AD at the foot of Jebel Hafeet by order of Sheikh Zayed bin Sultan, and was restored in 2004 AD. The construction of the dam came as a first attempt to harness the water flowing from Jebel Hafeet during the rainy winter, but it was replaced by the drilling of a deep well and the establishment of a hot water spring in the middle of the Green Mubazzarah tourist resort.
