Central Water Commission is the only agency doing flood forecasting in India. As per CWC’s Flood Forecasting website[i] the Data Flow Map has information about 226 Flood Forecast Sites in the country comprising of 166 Level Forecast Sites and 60 Inflow Forecast Sites. It also monitors 700 Flood sites, information made available through List Based Exploration and Hydrograph View, but no flood forecasting is done for these sites.
In order to better understand the CWC’s flood monitoring and forecasting work, in this article, we have given an overview of CWC’s flood forecasting and monitoring sites in South India. It includes state wise list of CWC’s Level Forecast, Inflow Forecast and level monitoring sites in South India. Similar report has been published for North India[ii] and North East India[iii] and East India[iv].
Tamil Nadu There are 3 Level Forecasting, 48 Level Monitoring and 14 Inflow Forecasting sites in Tamil Nadu State. Out of total 65 sites, 19 Level Monitoring and 2 Inflow Forecasting sites are inactive. MWL information is given only for 1 Inflow Forecasting site out of 14. IRRUKKANKUDI, Sathanur and Gomukhi sites are repeated with incomplete information. Out of 48, HFL figure and date is not provided for 25 Level Monitoring sites.

This is about two states, Andhra Pradesh and Telangana (the latter being 29th Indian state formed in 2013 after a protracted struggle). Since the discussion is on the state of rivers, it may be noted that these are two states whose historical trajectory is intrinsically linked to the history of, mainly, two major rivers—Krishna and Godavari, although the two states have many other rivers.
In fact, Telangana, was created after many years of struggle and out of one basic river-water discourse: over the utilisation of Godavari river and unequal development of the Godavari delta region vis-à-vis Telangana on account of the numerous irrigation projects and hydro-power projects commissioned and implemented in the coastal Andhra region.
In the wake of the recent contention between Telangana and Andhra Pradesh and the resolution over utilisation of the other river, Krishna, the state of rivers in Andhra Pradesh cannot be seen without addressing the same in Telangana, which have a historical trajectory that necessitates an understanding of the two states together while discussing rivers.
To some extent, this report looks at the politics over rivers and the contemporary development paradigm, involving construction of hydro-electric projects and several subsidiary projects using rivers, as one of the major threats to the life of rivers. These projects also add to pollution, displacement, protracted battles, sometimes involving violence, such as the one we are witnessing over Cauvery river between Karnataka and Tamil Nadu, where even Tribunals seem to have failed.
