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

2: GoodDam and catchment reference
Dam / barrierAlqueva
Completed2002
Dam height96 m
Dam length458 m
Reference capacity4150 mil. m³
Reference surface244,16 km²
Catchment55.045 km²
Elevation80 m a.s.l.
Long-term mean flow144,37 m³/s
Reference main useHydroelectricity
The mean flow is a WaterGAP/HydroSHEDS 1971–2000 model reference from Global Dam Watch, not today's inflow or release. Blank fields remain unfilled where no reviewed dam match exists.
