Across lake zones, total rainfall since the beginning of the monsoon ranges between 2239 mm (Middle Vaitarna) and 4011 mm (Tulsi), reflecting widespread and consistent rains over the catchment areas.
According to remarks in the report, most lakes started overflowing between 16 and 23 August, including Tulsi, Vehar, Tansa, and Modak Sagar. The gates of Upper Vaitarna, Middle Vaitarna, and Bhatsa were opened in August, and in the case of Modak Sagar, as early as 9 July 2025.
