South Africa’s Vaal Dam recorded a storage level of 102.78% on Wednesday, 15 April 2026, edging down from 103.04% during the two preceding days. According to the latest data published byThe Reservoir, a Water Resource Information Centre serving the Catchment Management Forums of the Upper Vaal Water Management Area, the dam has been running above full supply level since at least 13 April. “Level: 102.78%,” the centre reported for Wednesday, noting that one sluice gate had been opened to manage the surplus.” Inflows into the dam have remained relatively steady across the three-day period, registering 61.3 m³/s on Wednesday, down marginally from 62.5 m³/s on Tuesday and 64.2 m³/s on Monday.

The most notable shift in Wednesday’s data was an escalation in releases from the dam. Outflows were reported at 113.8 m³/s on 15 April, an increase from the 10.5 m³/s released on both Monday and Tuesday, when no spill gates were open. The Reservoir recorded an outflow of 10.5m3/s for each of those days.
