Al-Musk Lake (Arabic: بحيرة المسك) was an artificial sewage lake east of Jeddah, Saudi Arabia, a city that (at the time) lacked an underground sewage system.[1] The lake was established by the Municipality of Jeddah in the 1990s.[2] Over time, the lake reached dangerous levels, and in 2005, a concrete precautionary dam was erected to prevent spillover into the city.[3]
In 2010, the lake was drained by Saudi Arabia's National Water Company, acting under government instructions.[2] Despite having been drained of sewage, a 2017 scientific study concluded that the site remained environmentally contaminated.[4]
