Key Facts

Waduk Gajahmungkur is a major reservoir located in Wonogiri Regency, Central Java, Indonesia. Situated approximately 30 kilometers southeast of the regency's capital city of Wonogiri, this artificial lake was created by the construction of the Gajahmungkur Dam across the Keduang River, a tributary of the Bengawan Solo River. The reservoir serves multiple critical functions for the region, primarily functioning as a vital water source for irrigation across thousands of hectares of agricultural land in Central Java, while also providing flood control for downstream areas and generating hydroelectric power. With a surface area of approximately 8,800 hectares when at full capacity, Waduk Gajahmungkur has become an important economic and recreational asset, supporting local fisheries and attracting tourists who come to enjoy boating, fishing, and the scenic landscapes surrounding the reservoir. The creation of this reservoir in the 1970s required the relocation of numerous communities, transforming the local geography while establishing a crucial water management infrastructure that continues to benefit the agricultural productivity of Central Java.
