SUMMARY
OF THE WATER VOLUME, AND PROGRESS OF WATER SHORTAGE
PREVENTION AND MITIGATION MEASURES IN RAYONG AND PROVINCES FOR 2015-16
CHONBURI
On February 2nd 2015 the combined water volume in the 3 reservoirs is = 188.58 MCM. (68.5%) • Decrease since yesterday= -1.05 MCM. •
Water diversion through tunnel from the KlongYai res. to NongPlaLai res. presently stopped due to Klong Yai Res. level being lower than Nongplalai Res.
Water transfer from Prasae Reservoir to Klongyai Reservoir Currently, pumping stopped for pipeline construction
The Royal Irrigation Department has temporarily raised the spillway level at Klongyai and Prasae Reservoirs by 0.50m
