As of 13 Nov 2026 Data from the National Hydroinformatics Data Center (ThaiWater), HII, refreshed every 10 minutes
Storage this year and last
Down 97.4 million m³ over the last 7 days
1,798 million m³ less than on the same day last year
- 2026
- 2025
- Normal storage 9,510 million m³
- Upper and lower rule curves
Daily storage from the National Hydroinformatics Data Center (ThaiWater). The rule curves are the range the dam is meant to be kept within through the year.
Try the reservoir
Change the inflow, the release and the rain over the dam's catchment, and see what the reservoir would do over the next 90 days, starting from today's figures.
The reservoir would fall by 13.1 million m³ a day
Over the next 90 days the reservoir reaches neither normal storage, a rule curve nor dead storage
In 90 days it would hold about 6,334 million m³ (66.6% of capacity)
- Actual storage
- Projected
- Normal storage
- Upper and lower rule curves
- Dead storage
Today's storage, plus the inflow and the rain that runs in, less the release, a day at a time; evaporation and seepage are left out. It is arithmetic on the figures you set, not a forecast.
