Gajah Mungkur Reservoir (Dam) (Indonesian: Waduk Gajah Mungkur) is a water reservoir located at Pokohkidul in the Wonogiri Regency, Central Java, of Indonesia. It was constructed by redirecting the Bengawan Solo River, the longest in the Java Islands, which originates from The Gajah Mungkur Mountain. The maximum inundation area of Gajah Mungkur Reservoir is 8,800 hectares (producing the largest lake in Java by surface area) and covers parts of the seven administrative districts (kecamatan) of Wonogiri, Ngadirojo, Nguntoronadi, Baturetno, Giriwoyo, Eromoko, and Wuryantoro.[1]
The reservoir is used for irrigation, hydroelectric power, source of drinking water, tourism, aquaculture, and fisheries.[2] Various fish may be found in the water, including parrotfish, wader pari, tawes, and patin jambal.[3]
