These  stations  cover  20  major  river  basins  in  23  States  &  2  Union  Territories.   In respect  of  rivers  common  to  Nepal  and  India  namely,  Sharda,  Ghaghra,  Rapti,  Gandak,  BurhiGandak, Bagmati, Kamala, Kosi, Mahananda, etc.flood forecast is formulated considering the rainfall in the catchment of  rivers  in  Nepal  utilizing  meteorological  and  hydro-meteorological  data  available  through  website  of Department of Hydrology & Meteorology, Government of Nepal. These data are updated on an hourly basis during monsoon season and are utilised directly in the 24 hour flood forecasts being formulated by Divisional Flood Control Rooms of CWC in Lucknow and Patna.

There  are  40  level  forecasting  stations  and  3  inflow  forecasting  stations  in  Bihar  as  per  details  given  at Annexure - I . Dissemination of flood forecasts is through a dedicated website https://ffs.india-water.gov.in/.

CWC is also issuing five-day advisory flood forecast on its web portal https://aff.india-water.gov.in/ through rainfall-based mathematical modelling for major river basins of the country covering 199 water level and 134 reservoir inflow forecast stations including 40 level and 3 inflow forecasting stations in the state of Bihar. The system is developed using computational techniques for flood forecasting which is updated every three hours for all the stations simultaneously in automatic mode during monsoon season.
