Phnom Penh, Cambodia, is situated on the confluence of four rivers: the Upper and Lower Mekong rivers, the Bassac River and the Tonle Sap river. The surrounding area is flat and low-lying, subject to annual flooding. Natural lakes formed as the rivers changed course over time and communities grew up around the edges of these lakes, using them for fishing and aquatic agriculture.
In the 1980's, after the Khmer Rouge lost control of much of Cambodia, displaced people flowed back into the capital city of Phnom Penh. Returnees created new settlements and villages when vacant housing was no longer available. One group of returnees consisted of traditional musicians looking for a central location to resume teaching their art. This group of musicians moved into the Bassac Theatre close to the Bassac and Mekong Rivers. Gradually more returnees gathered around this community and in 2005 the Dey Krahorm village consisted of an estimated 800 families.
