The 21 strategic reservoirs named in DGREH note N° 2026-12/DGREH of 30 September 2026 (Table 7). Capacity, stored volume and percent full are the note’s figures. The note says the volumes do not account for siltation. Table 6 of the June 2024 DGIH inventory prints 6,683,655,070 m³ for the 863 reservoirs that have a capacity figure; the report’s conclusion prints 6,661.12 million m³. The Table 6 total is the published denominator the listing used. The fill on this page is the capacity-weighted fill of these 21 reservoirs.
