Fig. 7 Precipitation (a) and water volumes in reservoirs
1B (b), 1A (c) and 3 (d) over the period 2011–2016.
Simulated water volumes are shown as blue lines,
observed data as red dots. 1B and 3 were not operational
until 2012. Data from 1B and 1A were used for
calibration while data from reservoir 3 were used for
validation. Note different scales on y-axes
