Bang Neow Dum reservoir currently contains 7.39 million cubic metres of water, of which 7.36mn is usable volume, reports the Office of the National Water Resources (ONWR).
The reservoir’s official capacity is 7.2mn cubic metres.
According to the ONWR, Bang Wad reservoir in Kathu is 96% full, with 9.82mn cubic metres of water, of which 9.55mn is usable volume. Bang Wad’s official capacity is 10.2mn cubic metres.
Meanwhile, Klong Kata reservoir in Chalong is 94% full, with 4.06mn cubic metres of water, of which 3.9mn is usable volume.
The ONWR does not list a capacity volume for Klong Kata, though most recent reports have yet to be updated from its last recognised capacity of 3.49mn cubic metres.
Krirksak Leenanon, Director of the Phuket branch of the Royal Irrigation Department, last month warned the reservoirs would be full by the beginning of October.
Following heavy downpours across the country, before the current spate of floods in the North, officials nationwide were ordered on Sept 19 to monitor water levels at all reservoirs at risk of overflowing, and to take any immediate action to prevent further calamity.
Mr Krirksak last month assured that when the time comes officials will start releasing water through the reservoirs’ spillways to make sure they do not overflow. However, he has yet confirm whether officials were already doing that.
“This will not affect people in downstream areas,” Mr Krirksak also assured.
Phuket has been listed among the provinces throughout the South to be on alert for more heavy rains and potential flash floods through to Saturday (Oct 12).
According to the Phuket branch of the Thai Meteorological Department (PhuketMet), Phuket so far has recorded only 47mm of rainfall this month, but more than 20mm in the past three days.
Phuket has already recorded 2,057mm of rainfall this year, PhuketMet also reports.
Last month was drenching for Phuket, with sporadic flash floods across the island as 664mm of rainfall fell across Phuket in September alone.
