See flood risk before changing water releases
This view combines operator-confirmed reservoir and release data with official rain and river forecasts, upstream and downstream conditions, warning levels and recorded actions.
Reservoir level and approved range
See the current level, today’s target and the flood safety line. Any approved change is saved as a new version.
Can we trust the data?
Every important value shows who provided it and when it was updated.
How water moves through the dam chain
This simple example shows the order of reservoirs and downstream river stations. The final system will use verified locations and tested water travel times.
Expected river level downstream
Show the full possible range with the approved alert level. Do not rely on only one forecast line.
Checks before an early release
A proposed release must pass all five checks.
Compare release choices
Always compare each choice with making no release change. The effect on electricity supply comes from EDL’s energy analysis.
| Choice | Highest river level | Arrival time | Space for floodwater | Change in energy | Risk |
|---|---|---|---|---|---|
| No action | 0.28 m above alert | 19:20 | 12% | Starting point | High risk |
| Plan A · slow release | 0.10 m below alert | 20:40 | 27% | +18 MWh | Check |
| Plan B · later release | 0.04 m below alert | 21:25 | 21% | +9 MWh | Check |
