Rawapening is a natural lake located close to a small city called Ambarawa in Central Java, Indonesia. It is surrounded by Mt. Merbabu, Mt. Ungaran, and Mt. Telomoyo. Although the word “rawa” literally means swamp, but Rawapening is really a lake. Unfortunately, the lake facing the problem of sedimentation and water quality degradation. Some environment experts said that the lake can be turn into dry land in the future if there are no actions taken to save the lake.
Anyway, the lake provides us beautiful scenery, especially early in the morning. We can also see the fishermen lives around the lake set out in their small “sampan”, for the lake is the main source of income for their daily living. They usually capture freshwater fishes and shrimps to be sold in the local market. Some of them collect water hyacinth (Eichhornia crassipes) to be processed further into crafts. Nowadays, they also start to cultivate freshwater pearls.
