Check dam storage today and which reservoirs are full
Tap a dam on the map and today's storage comes first, in a colour that tells its state at a glance: red at or above normal storage, amber when low. The same colours are used on the dam pins, the dam pages, link previews and in LINE.

How to use it
Tap a dam pin
Round pins are storage dams. The water inside rises with today's storage; red water means the reservoir has reached normal storage.
Read the top of the panel
The large figure is the share of capacity at normal storage. The bar has marks at 50% and 100%, and ends in an arrow above 100%.
Check inflow and release
Below it are the volume in the reservoir, the inflow and the release per day. When inflow exceeds release, the reservoir is filling.
See every dam at once
The dam storage page lists all dams in the same colours, or type Dams in LINE for the large dams, fullest first.
Good to know
- Red
- 100% of normal storage or more. Dams often release more at this point; follow the operator's announcements.
- Blue
- Above 30% and below 100%, the usual range.
- Amber
- 30% or less. The reservoir is low; water may need to be saved.
Where the data comes from
Dam storage is daily data from the National Hydroinformatics Data Center (ThaiWater), gathered from the Royal Irrigation Department and EGAT. Percentages are of capacity at normal storage.
Frequently asked questions
- How can a dam be above 100%?
- Percentages are of normal storage. Most dams can hold more than that, so figures above 100% happen; dams usually release more at that point.
- How often is dam data updated?
- Once a day, from the operators' daily reports.
- Why is there no figure today for some dams?
- Those dams are not in ThaiWater's daily storage report, so only their general facts are shown.
