An independent, non-commercial project. None of the data providers listed here takes part in it, sponsors it or endorses it.

Modeled and estimated values

Many values in the panels are not measurements. They come from global models and datasets, each for its own period, and are marked with * where they appear:

  • Discharge: natural long-term average for 1971–2000 (WaterGAP model). It does not reflect today's dam regulation.
  • Flow regime: GIRES v1.0 predictions (Messager et al., 2021), not observations.
  • Flooded area: mean annual minimum and maximum from satellite data, 1993–2004 (GIEMS-D15).
  • Population: 2010 estimate (GPWv4).
  • Dam regulation: storage of the reservoirs upstream (GRanD v1.1) as a share of the modeled natural annual flow. Above 100%, they can hold more than a year of flow. Capped at 1,000%.

Large dams regulate the Limay and the Neuquén today, so the flow in these rivers can differ a lot from the natural averages shown here.

The basin outline, the sub-basins and the courses of the named rivers were derived by this project from HydroBASINS and HydroRIVERS. Most names come from IGN, matched to the river network automatically, with a confidence level shown on each stream. They may contain errors.
