The Department of Water and Sanitation (DWS) has released its weekly dam levels report, showing the Integrated Vaal River System (IVRS) at 99.6% this week. Â Most key dams remain at or above full capacity, including the Vaal Dam, which increased from 100.9% to 101.6%. This consistent performance supports domestic, agricultural, and industrial water needs in Gauteng and surrounding regions.
Why it matters to you
High dam levels in the IVRS indicate a secure water supply for households, farmers, and industries. Stable storage levels help buffer against temporary dry spells, rising temperatures, and increased water demand. This reassures municipalities and residents that essential water services remain uninterrupted.
What you need to know
Key dam levels within the IVRS:
| Dam | Current Level | Previous Level | Notes |
| Vaal Dam | 101.6% | 100.9% | Supports urban and industrial supply |
| Sterkfontein | 100.1% | 100.1% | Strategic reserve for system resilience |
| Bloemhof | 95.3% | 96.5% | Supports downstream flows and agriculture |
| Grootdraai | 101.5% | 102.1% | Vital for upper Vaal catchment and power generation |
