Flood forecasting is an important activity during monsoon, considering the huge and increasing flood prone area, flood frequency, extent and flood damages. Accurate and timely flood forecasting can hugely help reduce the damages due to floods. Central Water Commission (CWC) is the only agency responsible for flood forecasting in India. To understand the CWC’s flood forecasting better, we have compiled the list of the various flood, inflow forecasting sites and flood monitoring sites in India.
In this compilation, we have given state wise list of CWC’s flood forecasting, flood monitoring and inflow forecasting sites, along with available details like rivers, sub basin, river basin, Warning level, Danger Level, High Flood Level, Full Reservoir Level, Maximum Water Level. As we see below, there are many gaps in this basic information for the sites that are part of CWC’s list.
JAMMU AND KASHMIR There are 3 flood forecasting and 1 level monitoring site in Jammu & Kashmir. There is no inflow monitoring site in the state. HFL details for Khanabal site on Jhelum are not given where the hydrograph for the site is active.

Summary:- Overall there are 144 CWC sites in 7 states of North India comprising of 48 Level forecasting, 91 level monitoring and 6 inflow measuring sites. Out of 144 sites 13 sites are inactive including 11 level monitoring and 2 inflow monitoring. With 87, Uttar Pradesh state has highest number of sites followed by Uttrakhand (28) and Himachal Pradesh (17). There is no CWC station in Punjab whereas Delhi has 3, Jammu & Kashmir has 4 and Haryana state has 5 such sites. Of 11 inactive level monitoring sites 6 are in Himachal, 1 in Uttarakhand and 4 in Uttar Pradesh.
In most of the inflow forecast sites, the full information including level, inflow, outflow through canal, outflow through river is not given. It is also unclear at what stage the inflow forecast is triggered. Even the CWC’s Standard Operating Procedure of flood forecasting this year does not throw light on this, except vaguely stating that this is triggered by threshold values, not mentioning what are the threshold values for different cases.

MAJOR GAPS There are major gaps that we can see in CWC’s flood forecasting in North India.
- For example, CWC has no sites in Punjab and Chandigarh.
- In whole of Chenab basin that spans across Himachal Pradesh and J&K, CWC has no sites.
- Even in Sujlej, Ravi and Beas basins, CWC has no flood forecasting sites.
- In Sutlej and Beas basins, it has some flood monitoring sites, but in Ravi Basin, CWC does not have a single monitoring site.
- In whole of Uttarakhand, CWC has no flood forecasting sites in Bhagirathi, Ramganga, Sharda or Yamuna basins. The only Level Forecasting sites it has, are two on Ganga and one each on Alaknanda and Mandakini sub basins.
- In whole of Ghaggar Basin, spanning from Himachal Pradesh through Chandigarh, Punjab, Haryana, and then beyond North India, CWC has no sites at all. This basin suffered huge floods less than a decade ago.
There are many other issues with respect to the actual flood forecasting and monitoring by CWC and its website, which are not dealt here.
