Storage divided by the current net draw. These lakes publish no inflow readings, but the storage record shows the monsoon at work: up 342 mcft/day over the last 7 days. The days figure is a floor - it assumes the rain stopped today.

Upper-bound estimate: storage counts the full live water in the five state-owned dams, part of which serves users beyond BMC. Storage data: Maharashtra WRD Pravah portal→
