DISTRIBUTION IN CAMBODIA
- the dolphins' distribution in the dry season is thought to be restricted to the upper
reaches of the Cambodian Mekong from Kratie to the Lao/Cambodian border (including Chiteal
pool which lies on the Lao/Cambodian border).
- during the wet season, dolphins distribute throughout the Mekong River, south to at
least Phnom Penh and probably into Vietnam, and up into major river systems (such as the
Sekong and Sesan).
- the presence of Khone Falls (5 km north from the Lao/Cambodian border) prevents any
further movement north of the population.
- During the early 1970s, Irrawaddy dolphins were regularly recorded in Tonle Sap
Great Lake. It is believed that due to direct hunting in the mid 1970s and intensive
fishing pressure, dolphins are no longer found in significant numbers (if at all) in Tonle
Sap Great Lake.
- Kampi pool is one of the most important areas for the survival of the dolphins in the
- There are seven other important pools from Kratie to the Lao/Cambodian border, where
dolphins reside during the dry season. These areas can be seen on the map the red
dots are the areas where dolphins have been sighted during surveys in 2001.
