While India has received 874.6 mm rainfall which falls in normal[i] category in just concluded south west monsoon season, there have been at least 27 incidents of rivers crossing the Highest Flood Levels (HFLs) ever recorded in the past and attaining new HFLs in 5 river basins (some composite basins) in India, as recorded by the Central Water Commission (CWC) Flood Forecasting site[ii] during the monsoon.
The maximum 12 such instances have taken place in Ganga basin followed by 6 in west flowing rivers Tapi to Tadri basin, 5 in Godavari, 2 in West Flowing rivers Tadri to Kanyakumari basin and 1 each in Subernarekha and Tapi basin.
For past three years, SANDRP has been tracking the HFL breach incidents during monsoon season. The analysis of such HFL breaches in 2018[iii], 2019[iv] and 2020[v] can be seen on our website.

A large number of stories this week remind us that India urgently needs national urban water policy.
The water footprint of urban areas is gradually on the rise. The cities have several problems with management including destruction of water sources, groundwater exploitation, poor performance in treating and recycling the polluted water, pollution and encroachment on water bodies etc. To fulfil their growing demands new dams, barrages and check dams are being planned, proposed and built on the rivers in faraway places, which is in turn displacing and depriving the local people of equitable water share.
Even before onset of summer, the Army in Sagar district have started patrolling Chitora dam to prevent water thefts (denying farmers to take dam water for irrigation).

This article provides and overview of flood forecasting work of Central Water Commission (CWC) in 2019 after looking closely at each site details for the five regions of India: North East[i], East[ii], North[iii], West[iv] and South[v] India.
The table below provides an overview of number of Level Forecasting, Level Monitoring and Inflow forecasting sites as per CWC’s FF website during 2019 floods for all the states and regions of India.

Indian media never seems to report this, but IMD (India Meteorological Department) also provides river basin wise rainfall figures for South West Monsoon, also for other seasons. As in the previous years, here is an overview of the river basin wise rainfall during just concluded SW Monsoon 2019 (June-Sept 2019, though the monsoon started withdrawing only on Oct 9 and has not yet fully withdrawn from across India as I write this on Oct 15 2019), like the way we have been doing for the last three years[i]. Our earlier monsoon 2019 articles provided monsoon over view[ii], state wise rainfall figures[iii] and Marathwada specific situation[iv].
It’s not clear why Indian media does not report river basin wise rainfall figures, since that is arguably, the most appropriate way to look at the rainfall figures, since river basins are the hydrological units and the run off from the rainfall ends up in the rivers, and creates floods many times, as happened during 2019 monsoon. There could be issues of quality of the river basin wise rainfall figures, but that is true for all IMD’s rainfall figures at some level or other.

Central Water Commission (CWC) is the only agency doing flood forecasting in India. This article attempts to present an overview of CWC’s flood forecasting and monitoring sites in West India. It includes state wise list of CWC’s Level Forecasting, Inflow Forecasting and level monitoring sites in 5 States in West India: Rajasthan, Gujarat, Maharashtra, Madhya Pradesh, Goa. Similar report has been published for North India[i] and North East India[ii] and East India[iii]. A similar effort was made last year which can be seen here: Overview of CWC Flood Forecasting Sites 2018: WEST INDIA.

The new government at the centre, headed by Shri Narendra Modi, if we go by the signals so far, is likely to push the mega project agenda including Inter Linking of Rivers (ILR). It also seems that Gadkari may continue to be the Water Resources Minister, if we go by the statements and signals so far. Both these steps would be wrong. The PM has said he wants to provide piped drinking water to everyone in the country in his new term. Such one size fits all solutions are likely to create more problems than solutions, as we can see from the dumping of honey sucker tankers close to drinking water sources, thanks to building of crores of soak pit toilets.
If the government wanted to listen, this weekly bulletin (like any other week) from SANDRP provides enough food for thought. Very large part of India, including huge parts of big dam building states of Gujarat and Maharashtra are in grip of drought. Like they have been repeatedly over the last few years. ILR is an extension of the big dam agenda and no amount of false promises of Godavari water are going to fetch votes, as they did not for the BJP in current elections in Tamil Nadu or Andhra Pradesh. Similarly big hydro is no longer viable, and pushing them either in Ganga basin or in North East India will only invite dis-satisfaction, destruction and distress. Big dams are making the floods worse as Kerala example showed in Aug 2018, among many others. We can choose to close our eyes to these realities, but that wont change the realities.

- Gujarat suffering due to political use of water for elections in 2017.
- Rajasthan given more water for elections there in 2018. Will Punjab, Haryana suffer now?
- Kerala drought: how much could have been reduced if dams were operated more prudently?
- North Interior Karnataka is suffering, but Krishna basin dams are almost full? Issue of unsustainable cropping patterns, groundwater overuse, and neglect of recharge & regulation?
Gujarat Water scarcity looms large with state receiving only 74% rainfall so far
- Kutch and North Gujarat are likely to face severe water scarcity this year, officials said. The Kutch region has received a mere 26.51 percent of average rainfall so far, while North Gujarat has received 42.93 percent, central Gujarat 66.83 percent, Saurashtra 72.20 percent and South Gujarat the highest 94.79 percent.
- However, the Sardar Sarovar Dam is filled up to 125.82 meters, and it can provide drinking water for the entire state till the next summer, the govt said. As per Govt. storage in Sardar Sarovar Dam on the Narmada, which will be enough to meet the state’s need for drinking water through the next summer.
- The Narmada water will also be used to fill up empty dams in Saurashtra including Aji 1, Macchu 2, Vadod and Ankadia through the Sauni scheme, officials said.
- “The state govt will provide 20,000 cusecs water for the next 20 days to save the crops in water-starved areas,” Deputy CM Nitin Patel told reporters in Gandhinagar said.
- “We plan to fill up 400 big and small ponds in North Gujarat by Narmada water through canals and pipeline network of the Sujlam Suflam scheme,” he said.
- “We also plan to fill the dams in Saurashtra region and provide water for irrigation from Narmada Dam under the SAUNI scheme,” he said. https://www.firstpost.com/india/water-scarcity-looms-large-in-gujarat-with-state-receiving-only-74-rainfall-so-far-this-monsoon-says-government-5188271.html (15 Sept. 2018)

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 other sites, information is 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 West India. It includes state wise list of CWC’s Level Forecasting, Inflow Forecasting and level monitoring sites in 5 States in West India. Similar report has been published for North India[ii] and North East India[iii] and East India[iv] and South India[v]. This is the last part in the series.
