English: A Thai fisherman casts his net on Khao Sok Lake, in Kao Sok National Park (south-central Thailand, between Surat Thani and Phuket). This sprawling lake was formed by Chiew Laan Dam. The 48-year-old fisherman lives alone on a raft house on the lake. He explained that the National Park officials rarely allowed such homes to be built any longer, but he had been here for 10 years and was grandfathered in.
