WITH temperatures expected to climb even higher in the region as February approaches – historically the hottest month in Zululand – the levels of some major dams remain low with winter approaching.
While good rains have fallen over the last few weeks and the veld has turned to a bright green, consumers are still advised to continue using water sparingly.
This situation will be exacerbated by the high levels of evaporation, especially at the shallower dams where large surface areas in relation to depth play a role.
The end of the holidays will also play a role with increased water use by residents and businesses.
While it may be argued that the holidaymakers have returned home so there should be a respite, this is not necessarily the case as businesses start up and with it, an increase in water consumption.
The largest dam in southern Zululand, Goedertrouw in the Nkwalini Valley was still low at only 49.4% last Monday.

This is up on the previous week’s figure of 47.3% and last year when the dam was 45.8% of its full storage capacity.
Good rains last week and on Sunday may push the level over 50%, but as the rainy season is already nearing its end, it does mean the region could possibly go into the winter with the dam still at an unhealthy level.
Pongolapoort Dam on the Phongolo River with a capacity of 2267.1 mcm is at 42.4%, which is exactly the same as last year and the previous week.
The Bivane Dam near Louwsburg and the Klipfontein Dam outside Vryheid are at 69.7% and 73.9% respectively.
The exception is further north where the Hluhluwe Dam, with a capacity of 25.9 million cubic metres (mcm) compared to Goedertrouw’s 301.3 mcm, is 98% full, eight per cent up on last year’s figure.
Drownings
People looking for relief from the heat by swimming in dams and rivers poses a real threat to life.
Especially at risk are children who possibly cannot predict the dangers of swimming in fast-flowing rivers or in dangerous sea conditions.
Dams and swimming pools can also be treacherous, especially when the depth and possible undercurrents are unknown.
Many open water places do not have lifeguards, adding to the risks.
As schools open this week and children have rivers to cross, either because the bridge is flooded or a shortcut is preferred, care needs to be taken.
Parents and older siblings have a role to play and younger children should always be under their supervision when near open water.
