Notable for its expansive water body, small islands, surrounding hills and developed tourism area, it is a major recreational and scenic landmark in southern Central Java.

Visitors can expect a vast reservoir with calm water, scattered small islands and hilly surroundings. The main tourism area on the northern shore offers viewpoints, lakeside promenades, boat jetties and food stalls serving freshwater fish. Visitors can take short boat rides around the reservoir, enjoy lakeside sightseeing and photography, observe fishing activities and view the dam structure. The area is open and breezy with panoramic water and hill views.

Constructed between 1976 and 1981 by damming the Bengawan Solo River to control downstream flooding, provide irrigation for agricultural land and generate hydroelectric power. The dam and reservoir were inaugurated in 1981 and named Gajah Mungkur.

The reservoir is an important livelihood source for surrounding communities through fishing, aquaculture and tourism. It is a well-known local recreation destination and a landmark associated with Wonogiri identity, frequently visited for family outings and lakeside culinary activities.
