This market resolves YES if the Vaal Dam storage level stated in the Department of Water and Sanitation weekly report for the reference week is 100.0% of full supply capacity or higher. It resolves NO in every other case.
Settles from: Department of Water and Sanitation Weekly State of the Reservoirs report (https://www.dws.gov.za/Hydrology/Weekly/Province.aspx). Closes 2026-11-10 12:00 SAST. Decided 2026-11-20 12:00 SAST. The Vaal Dam is the primary water source for Gauteng and the anchor of the Integrated Vaal River System. Levels above 100 per cent of full supply capacity are normal after good rainfall and appear as such in the weekly report; this series does not cap at 100.

If any of the following happens, the question is voided and every stake goes back. It scores for nobody either way.
The Department of Water and Sanitation does not publish a Weekly State of the Reservoirs report covering the reference week within 21 calendar days of the customary publication date; The Vaal Dam is omitted from the report for the reference week; The basis on which full supply capacity is calculated for the Vaal Dam is restated, such that the published percentage is not comparable with the preceding repo
Think this reads two ways? and we will tighten the wording or void it.
A person reads every one of these. Tell us what happened and we will come back to you.
