The levels of the Integrated Vaal River System (IVRS) have increased, as the 14 dams within it continue to remain relatively stable. This comes after it saw a decline in the past two consecutive weeks.
According to the Department of Water and Sanitation’s state of reservoirs report, the system (IVRS) has notched up from last week’s 91.6% to 92.5% this week. This week’s levels are a vast improvement from last year at the same time when the system stood at equally stable but low 65.7%. Despite not seeing any change in levels for the second successive week, the iconic Vaal Dam and the critically important Grootdraai Dam persist to float at 104.4% and 99.8% respectively. In the preceding period last year, the Vaal Dam was slightly above the 50% mark at 53.7% while the Grootdraai Dam sat at extensively higher levels of 94.1%. The Bloemhof Dam continued its upward trajectory as it went up this week to a massive 106.1% from a similarly impressive 102.9% last week. Compared with last year’s levels of 86.1% during the same week, this week’s levels of the dam indicate a sustained rise in recent weeks. In the Free State, the levels of the Sterkfontein Dam are increasing weekly. This week, the dam climbed from last week’s 97.8% to edge just a few notches below the 100% mark at 98.1%. During the same time last year, the dam was 93.0%. Judging by its present levels, the Lesotho’s Katse Dam has turned the corner of worst levels last year when it was at a paltry 33.3%. Since then, the dam has risen in leaps and bounds to reach 78.9% this week, up from last week’s 78.0%. Another dam in Lesotho, the Mohale Dam, is continuing to replenish its levels despite lagging behind compared to the Katse Dam.In a shrunken state of 12.3% this time last year, the levels of the dam are increasing albeit at a snail’s pace. Presently, the Katse Dam is at 40.7%, up from 39.8% last week.
The other dams that form part of system are substantially higher this week and have contributed to its overall levels. Their levels are as follows:- Woodstock – 100.2%
- Zaaihoek – 82.1%
- Jericho – 89.5%
- Westoe – 95.4%
- Vygeboom – 101.0%
