Remarks 1. Mar 2016 had dregging sediment in front of Mor Mui weir which place inside Klong Nam Dang canal. So it needed to stop divert water from Prasae reservoir for a whole month and adjust the water diversion plan from 8 MCM to 9 or 9.3 MCM per month started from Apr – Sep 2016 2 2. On Oct – Dec 2016 Plan to divert water can be change depend on water situation
