If we speak of lakes, a Great Lake of Cambodia is the Tonle Sap Lake, which we can see at a glance very large if we go to a map. During the rainy season, Tonle Sap Lake is one of the largest freshwater lakes in Asia, but remains dry almost half of the year.

This lake decanted into the Tonle Sap River, which meanders toward the southeast, merging with the Mekong River in the Chaktomuk, meeting place of face to Phnom Penh. During the rainy season, there is a phenomenon that causes the river to reverse direction, leading to greater filling of the lake instead of draining. In this phenomenon, the engine is the Mekong River, which will swell with snow melt and run off of monsoon rains in the rainy season. This causes major flooding in the wooded surroundings and a plain is rich in living species, because there is forged a protected ecosystem.
In this ecosystem on which they commented, live more than 200 types of fish, several types of birds, crocodiles, turtles, monkeys, otters and various wild animals.
The Lake is as expected, also important in trade, as this provides more than half the fish consumed in Cambodia. People living around the lake have enabled their homes to cope with this issue adequately the flood, the rise and fall of the river, and to develop fisheries.
The lake is just 15 miles south of the city of Siem Reap. You can take a ferry between Phnom Penh and Siem Reap, across the lake and the village of Chong Khneas. In the area there are several ways to see the culture and wildlife. It just depends on the availability of time and interest.
