Sediments Entering Tonlé Sap, Cambodia

12.9N 104.0E

February 7th, 2012 Category: Lakes

Cambodia - December 17th, 2011

The Tonle Sap is the largest freshwater lake in Southeast Asia. It is of global significance and was nominated as a Biosphere Reserve in October 1997 under the Man and Biosphere Program of UNESCO Here, sediments can be seen entering the lake from rivers along the northern shoreline.

The Tonle Sap’s watershed supports an estimated 3 million Cambodians, most of whom derive subsistence-level incomes mainly through fishing from the lake. The Tonle Sap’s natural resources are coming under pressure from exploitation of the fisheries but also firewood collection, agricultural encroachment, and hunting and collecting of wildlife resources.

Tonlé Sap During Middle of Dry Season, Cambodia

12.9N 104.0E

January 14th, 2012 Category: Lakes

Cambodia - January 14th, 2012

This APM image shows the western part of the Tonlé Sap (loosely translated as “Great Lake”) and surrounding floodplain. The Tonlé Sap is the largest freshwater lake in South East Asia, and is part of a complex lake and river system.

The Tonlé Sap is unusual for two reasons: its flow changes direction twice a year, and the portion that forms the lake expands and shrinks dramatically with the seasons. From November to May, Cambodia’s dry season, the Tonlé Sap drains into the Mekong River at Phnom Penh. However, when the year’s heavy rains begin in June, the Tonlé Sap backs up to form an enormous lake. This image shows the lake towards the middle of the dry season.

Cambodia - October 29th, 2011

The Tonlé Sap, visible as a light green area in the center of this image, is a combined lake and river system of major importance to Cambodia. It is the largest freshwater lake in South East Asia and an ecological hot spot that was designated as a UNESCO biosphere in 1997.

Cambodia and Thailand - March 5th, 2010

Cambodia and Thailand - March 5th, 2010

This image of Southeast Asia includes parts of Myanmar, Thailand, Cambodia, Vietnam and Laos. Upon opening the full image, some fires are visible southwest of the  Tonlé Sap, a large lake in Cambodia. Some smoky haze from other fires in the region can also be observed in the upper left quadrant.

The Tonlé Sap, appearing tan and green from sediments, here, is the largest freshwater lake in Southeast Asia, occupying a large depression. It is part of a combined lake and river system that is particular in that its flow changes direction twice a year.

Fires Near Tonlé Sap, Cambodia

12.9N 104.0E

March 9th, 2010 Category: Fires, Lakes, Rivers

Cambodia - March 5th, 2010

Cambodia - March 5th, 2010

The Tonlé Sap, in Cambodia, is a combined lake and river system and the largest freshwater lake in South East Asia. The lake occupies a depression created due to the geological stress induced by the collision of the Indian subcontinent with Asia. A cluster of fires is visible here to the southwest of the lake.

The combined system is peculiar due to the fact that its flow changes direction twice per year. However, in recent years the building of high dams in Southern China and Laos has threatened the strength and volume of the reverse flow into Tonlé Sap; a phenomenon that environmentalists have been slow to recognize or raise concern about. Already fish catches are significantly down.
