Living on the water, 14-year-old Moeun Sambor cooks a fish dinner for her family in the floating village of Chong Kneas on Tonle Sap. During the low-water season, as many as 5,000 people in Chong Kneas live on the lake on tethered houseboats, without access to electricity or sanitation. When waters rise, villagers move to stay close to the shoreline.
