What is happening now
The current flow balance is unavailable
The operator has not published both sides of the balance for this observation.
This compares two published flow rates. It is not a measured storage change, and the feed does not identify whether outflow passed through turbines, an outlet or a spillway.
Latest observation—Operator-local timestamp
Current outflow— m³/sOperator-reported total outflow
Current outflow ÷ inflow—Needs both flows
Operator flow context—Q1 is a reference flow, not a safety limit
