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 rise by 0.3 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 305 million m³ (96.9% of capacity)
