Legends for various Tabs in CWC Flood Forecast Information :
This is a website for Central Water Commission’s Flood Monitoring and Forecast dissemination. This can be explored using map based exploration or list based exploration or Hydrograph View.
Map can be used as a tool to find information of 249 CWC Flood Forecasting Station consisting of 174 Level Forecasting Stations for towns/important villages and 75 Inflow Forecasting Stations for Dams/Reservoirs. List Based exploration or Hydroghraph view should be used for information of all flood monitoring stations around 700 including Flood Forecasting Stations. The Colour of any point signifies the basic Characteristics of the Station. Green is for Flood Level Forecast Station basically important towns/villages and Blue is for Inflow Forecast station basically a dam/reservoir/barrage/weir etc.
These colours will be dynamically changing for Flood Level Forecast Stations as per the river water level with respect to Warning Level (WL), Danger Level (DL), Highest Flood Level (HFL). Normally latest dynamic information is available during flood period 1st May/1st June to 31st October/31st December every year.
“Yellow” when the river is flowing in Above Normal Flood: when river water level is at or above WL but below DL
“Orange” when the river is flowing in Severe Flood : when the river water level is at or above Danger Level and below HFL.
“Red” when the river is flowing in Extreme Flood : when the river water level is at or above HFL
HFL is updated on an yearly basis before start of the flood season. Newly attained HFL during the flood season of a particular year in any station will be updated in the next year before start of the flood season.
On clicking a particular station, a window opens showing the static information of the station. The latest available dynamic information such as water level and flood forecast issued are also displayed in the window.
