Cape Water and Dams – monthly report nr. 125
as at 29th October 2018
Here are the predicted levels of the total amount of water that could be stored collectively in the six main SW Cape dams at the end of each month through to next winter (green shaded area), following the actual levels for the year-to-date (brown shading), and compared with the actuals from the periods of the prior year (blue shading).
At the moment we are assuming a normal average weather and annual rainfall patterns, an easing back to level-3 restrictions and the full allocation of irrigation water to the agricultural sector.
The model currently indicates that combined dam levels could drop to around 400 M.cuM of water (from the present level of 664 M.cuM) by early May, 2019 and that thereafter replenishment of the dams would commence as winter rains arrive.
.
The following chart produced by City of Cape Town shows the progressive change in the total amount of water stored graphically indicates how we have got to this point as the winter rains have replenished the main dams.

The shaded danger zones will now start to change their shape and should decline as the dry summer period passes and the following winter draws ever nearer.
