Mangla Dam

As of October 27, 2026, Mangla Dam is at 54.6% of useful capacity, holding 4,972 hm³ of 9,112 hm³. That live volume plus 1,234 hm³ of dead storage is 60.0% of the 10,345 hm³ total capacity. At this level the reservoir is within its normal operating range.

Over the most recent week on record the fill level has fallen by 1.2 percentage points.

Across the readings we hold for Mangla Dam — 162 data points between May 18, 2026 and October 27, 2026 — the level has ranged from a low of 30.4% (June 30, 2026) to a high of 77.9% (September 8, 2026). On average the reservoir is fullest around September and at its lowest around May.

The dam at Mangla Dam stands 138 m tall and is a embankment dam and was completed in 1967. It is operated by WAPDA primarily for hydroelectric power. It lies within the Jhelum basin at 33.127°N, 73.650°E.

Mangla storage is WAPDA's daily usable storage, the live water above the 1,050 ft minimum operating level. WAPDA does not publish a machine-readable feed, and the IRSA daily PDF gives the water level only. Where a day's WAPDA usable figure was published, that figure is stored. Every other day uses the IRSA level, which matches the WAPDA level on the days both exist, read through a piecewise-linear curve fitted to the 2026 WAPDA level and usable-storage pairs so those pairs are reproduced. The five-point gross curve minus 1.000 million acre-feet is not used; it sat about 0.35 million acre-feet below the WAPDA figures. Fill is the usable volume divided by the 7.387 million acre-foot live capacity in Flood Forecasting Division bulletin 124/26 of 15 October 2026. That bulletin and the WAPDA wire the same day both give 4.169 million acre-feet at 1,198.95 ft. The bulletin prints 57.29% beside that pair; 4.169 divided by 7.387 is 56.4%, which is the figure stored. The 24 and 25 October readings are the APP wires reprinted by UrduPoint, because the IRSA files for those days were not available: 1,197.50 ft and 4.082 million acre-feet (https://www.urdupoint.com/daily/livenews/2026-10-24/news-4986065.html), then 1,197.20 ft and 4.064 million acre-feet (https://www.urdupoint.com/daily/livenews/2026-10-25/news-4987139.html). Levels from 1,220.45 ft up to the 8 September peak of 1,222.35 ft are above the highest published pair, so those ten days continue the slope of the 1, 2 and 13 September pairs. Tarbela and Chashma use the same usable-storage basis. Their curves are fitted to the WAPDA wires, not to the old gross elevation curves.
