Boeung Kak Lake Report

Boeung Kak Area Drainage and Flooding Assessment (or try this link), 2008 Authors: Sally Benham & Ben Caddis

“Boeung Kak is a 90 hectare lake located within the Doun Penh district in the north of Phnom Penh city. A private developer, Shukaku Inc, has leased an area of 132ha, including the lake, from the Municipality of Phnom Penh and plans to fill and develop the area. This report investigates the potential impact on flooding as a result of the proposed development of the Boeung Kak area (BKA). Boeung Kak is a closed lake system, meaning that the catchment is not much larger than the lake itself, and there is no outlet for water from the lake. Rainfall onto the lake itself is stored within the lake until it evaporates or infiltrates.

The volume of this direct rainfall was estimated for a storm event in April 2008 at 360,000m3. This event was not noted as particularly large by residents of the lake. Following filling and development of the BKA, rainfall on the development is expected to be diverted to neighbouring areas downstream to the north. The anticipated increase in peak flood levels and flood frequency that would result without mitigation is considered unacceptable. Shukaku Inc released an Environmental and Social Impact Assessment in August 2008. This ESIA includes only vague plans for mitigation, such as ‘dig a canal 20-21m2 in area’. These plans do not appear to be based on sound engineering assessment. Further, Shukaku Inc disputes their obligation to mitigate the impact of their development.”
