Located between the Karak Governorate and the Amman governorate, between the cities of Karak and Madaba, there is a large crevasse which holds the infamous Sad Wadi Mujib, Wadi Mujib Dam in Jordan. Beginning construction in 1998 the dam is intended to supply water to Amman. The dam contains desalinated water from brackish wells found along the Dead Sea region. It finished completion 6 years later in 2004.

Using a special kind of concrete known as Roller Compact concrete (RCC) which is the same as normal concrete but with different ratios, the substructure is made of clay-core rock fill. According to a 1999 article published by the Middle East Economic Digest (MEED) the construction cost was about 45 million Jordanian Dinars ($67 million USD).

The historic Kings Highway, or highway 35, crosses the ridge of the dam allowing for ease of transportation along one of the earliest and most used highways in the country.

The creation of the dam was intended to ease the stress of the national water supply and sanitation of Jordan, which is categorized by extreme shortage of water supply. This has been a growing concern since the influx of refugees since the 1948 Arab-Israeli War, then the 2003 invasion of Iraq by the United States, and the 2011 Syrian civil war; the water resource has had to suffice for more than just the population of Jordan. According to a 2016-2017 study commissioned by the NGO Mercy Corps this is a small yet significant source of social tension between refuges and Jordanian nationals.

On the side of the dam closest to Madaba one can find atop the mountain a small hut in which trinkets, tea and coffee can be sold. This is also a magnificent place for one to sit and watch the sunset, as the view overlooks the large valley towards Wadi Mujib and the Dead Sea.
