Neak Loeang sits in Cambodia’s Mekong-Tonle Sap basin, the low-lying heart of the country where the wet season runs from roughly May through October and the Tonle Sap Lake’s famous seasonal flood pulse, in which the Tonle Sap River reverses direction each year, drives much of the region’s flooding.
A historic Mekong ferry crossing point, the town’s riverside position makes it one of the more flood-exposed communities in Prey Veng province. Major Mekong flood years, including 2000, 2011, and 2013, showed how a wet monsoon season upstream can raise water levels across this entire basin for weeks at a time, and Cambodia’s Ministry of Water Resources and Meteorology uses radar alongside river gauges to track both direct rainfall and the river system’s slower, larger rises.
