NOTES:
* For Reservoirs, discharges (Inflows/Outflows) are averages of 24 hours.
** Flood Classification: (applied on downstream discharge/Outflow)
"Mild" Categories
Low Flood: River flowing within deep (winter) channel(s) but about to spill threatening only river islands/belas
Medium Flood: River partly inundating river islands/belas
High Flood: River almost fully submerging islands/belas and flowing upto high banks/bunds but without
encroachment on the freeboard
"Danger" Categories
Very High Flood (VHF): River flowing between high banks/bunds with encroachment on the freeboard
Exceptionally High Flood (EHF): Imminent danger of overtopping/breaching, or the high bank areas have become inundated

*** (R) Signifies "Rising" Flood, (F) Signifies "Falling" Flood,
(S) Signifies "Stable" Flow Condition
NR stands for Not Received
+ Based on IRSA’s Daily Hydrological Data
++ For MCL of 1210.00 ft.
