SUMMARY OF THE WATER VOLUME, AND PROGRESS OF WATER SHORTAGE PREVENTION AND MITIGATION MEASURES IN RAYONG AND CHONBURI PROVINCES FOR 2014-15  On January 8th 2015 the combined water volume in the 3 reservoirs is = 215.23 MCM. (78.2%) • Decrease since yesterday= -0.99 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

 0 MCM pumped during January 7th  (Pumps stopped for pipe repairs)

 0 MCM accumulated volume to date (1 Jan 15 – 8 Jan 15 at 6:00 am)  20.30 MCM accumulated volume to date (1 Aug 14 – 

25 Dec 15 at 6:00 am)

The Royal Irrigation Department has temporarily raised the spillway level at Klongyai and Prasae Reservoirs by 0.50m
