7 February 2006
High levels, which came as a result of the current rains, have forced
officials of the Department of Water Affairs and Forestry to open some sluice
gates at the Vaal Dam to avoid flooding.
The inflow peaked at 1 200 cumec on 31 January 2006 and gradually abated to
the 300 cumecs once the dam level reached the 95% mark. The first sluice gate
was opened on 1 February 2006.
The dam slowly rose from a level of 98% on Friday, 3 February 2006, and
filled to the 100% mark on Sunday, 5 February 2006.
Due to a further rising of the dam level, a second sluice gate was opened
yesterday, 6 February 2006, and a third sluice gate was opened this morning, 7
February 2006, at 07h00. It is envisaged to open a fourth sluice gate by 12h00
on 7 February 2006.
The Grootdraai Dam was at 100.3% at 06:30 on 7 February 2006. The present
inflow is 60 cumec with an outflow of 125 cumec will be maintained for as long
as it is deemed necessary, where after the sluice gates will be adjusted to
cater for the need.
The benefit of the outflow has reached Bloemhof Dam, which had a level of 9%
and has increased to 35% and is expected to increase to more than 50% within
the next fortnight.
The increased flow rate poses no threat to people downstream. The river is
not expected to flood its banks.
There is no danger to residents downstream of the Vaal Dam and Grootdraai
Dam, however, campers and fishermen are warned to take caution.
