Several dams across South Africa have overflowed over the past two weeks‚ thanks to a significant improvement in rainfall‚ the Department of Water and Sanitation said on Wednesday.

"The rain was soft but intense‚ enough to soak the soil and replenish groundwater for basic use‚" the department said in a statement.

Improvements in the past two weeks have been noticed in most provinces‚ particularly Gauteng‚ Mpumalanga‚ Free State‚ North West and KwaZulu-Natal.

The report showed that national average dam levels have increased significantly from 70‚5% last week to 75‚2% this week.

In Gauteng the Vaal Dam level increased from 94‚7% to 103‚5% last week. The Integrated Vaal River System‚ consisting of 14 dams (including the Vaal) that serve Gauteng‚ Sasol and Eskom‚ increased from 83‚5% to 87‚6%. The system was at 86‚8% during the same time last year.

However‚ the Western Cape Water Supply System’s six dams that serve mainly the City of Cape Town decreased from 18‚3% to 17‚7%‚ the department said. The system was at 24‚4% at the same time last year.

"Theewaterskloof Dam continues on a week-on-week downward slide from 10‚4% to 10‚3%. Last year at the same time‚ the dam was at 21‚1%. Clanwilliam is the only dam that registered some improvement from 6‚2% to 6‚4%‚ while Voëlvlei remains stagnant at 14‚5%. The City of Cape Town‚ unlike most parts of the country‚ experienced insignificant rains last week."

The North West Province has a fair amount of water in its dams to sustain it through the dry season. The Crocodile West increased significantly from 83‚3% to 89‚6% in the period under review. The system was recorded at 97‚1% in the same period last year. Disaneng is down from 63‚2% to 62‚8%. Setumo is at 80‚3% and Potchefstroom is at 100‚8%.

Midmar Dam decreased from 101‚1% to 100‚5%‚ while Inanda has increased remarkably from 62‚8% to 70‚3%. This has led eThekwini Municipality to consider lifting water restrictions that have been imposed due to the drought.
