The Vaal Dam continues to inspire optimism for stable water supply this week as it indicated levels higher than last year’s during the same period. Last year it was at 41.0% and this week it is at 90.3%. The Vaal Dam is one of the 14 dams that form the Integrated Vaal River System (IVRS). On the strength of major dams having been replenished to decent levels, the system (IVRS) experienced a slight decrease from 85,6% last week to 85.0% this week. Last year at the same time, the system was at 62,2%.
