Phnom Penh is in the south-central region of Cambodia, and is fully surrounded by the [[Kandal province]]. The municipality is on the banks of the [[Tonlé Sap]], [[Mekong]], and [[Bassac River|Bassac]] Rivers. These rivers provide freshwater and other natural resources to the city. Phnom Penh and the surrounding areas consist of a typical [[Floodplain|flood plain]] area for Cambodia. Although Phnom Penh is at {{convert|11.89|m|ft|0}} above the river, monsoon season flooding is a problem, and the river sometimes overflows its banks.{{Citation needed|date=February 2025}} [[Boeung Kak]], Phnom Penh's largest freshwater lake, was controversially filled in 2010 to make way for property development.<ref>{{Cite news |date=2011-08-14 |title=Cambodia lake battle: How Boeung Kak became a puddle |url=https://www.bbc.com/news/business-14488100 |access-date=2025-02-23 |work=BBC News |language=en-GB}}</ref>
