- 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?
- 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)
Himachal Pradesh Rajasthan quietly given extra water by BBMB to improve BJPs Poll prospects A detailed story about how BBMB, controlled by Central Power Ministry, released excess water to BJP ruled Rajasthan this poll year, which has deepened the water availability at BBMB dams this year. This is not that the first time that the water releases have happened to achieve poll objectives. https://www.huffingtonpost.in/2018/09/16/rajasthan-quietly-given-extra-water-by-bhakra-dam-board-to-improve-bjps-poll-prospects_a_23528788/ (14 Sept. 2018)
Rajasthan Rainfall deficit in many districts As per IMD, Badmer district of Rajasthan has received rainfall 48 percent below normal till Sept. 16. Similarly rainfall deficit in Hanumangarh 58 percent so far. Jallor district is facing maximum rainfall deficit of 60 per cent less than normal. Likewise the rainfall in Pali district is 35 per cent below the normal and in Jaislmer is facing a rainfall deficit of 38 per cent. In Western Rajasthan it rained only 193 mm during entire monsoon season causing a deficit of 24 per cent below the normal.
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.

Accepting that reservoirs operation and flood management in India lack scientific supports, Madhavan Nair Rajeevan, Secretary, Ministry of Earth Sciences, in an interview has revealed that dams and water reservoirs need flood management systems that use scientific methods to understand when the time is right to open the gates.
“As per my understanding, no big reservoir has a decision support system. So we don’t know when to open them, how to open them… I am not attributing the Kerala floods to an individual. There is a common perception that in India most of the flood management systems are not supported by science… I am very sure we don’t have the decision support system and we need it.” https://indianexpress.com/article/india/not-just-kerala-no-scientific-dam-water-management-across-india-madhavan-nair-rajeevan-secy-earth-sciences-5322003/ (24 Aug. 2018)
In another interview he says that while Kerala records among the highest amounts of rainfall in the country, the State did not have a flood warning system in place. He added that while there were several sophisticated tools to anticipate extreme weather events, India still lacked a mechanism to effectively deploy them. https://www.thehindu.com/sci-tech/energy-and-environment/reservoirs-not-managed-using-a-scientific-decision-support-system-m-rajeevan/article24785253.ece (26 Aug. 2018)
Further in a detailed interview, he pitches for ‘decision support systems’ at dams, acknowledges the challenge of climate change, warn against repercussions of ‘fast-warming’ Indian Ocean. https://indianexpress.com/article/india/kerala-floods-m-rajeevan-ministry-of-earth-sciences-met-department-5324840/ (26 Aug. 2018)

Amid news of monsoon being normal, farmers in several parts in the country have started facing irrigation water problems affecting sowing of Kharif crops. Apart from, insufficient rainfall, mismanagement of water resources is turning the situation grim for them.
As per reports, water levels in Bhakra and Pong dams in Himachal has plunged to lowest in decades. As a result dam authority has issued advisory to lakhs of farmers in Haryana, Punjab and Rajasthan to use water judiciously. Some official also said that the beneficiary states lacks efficient water management practices which is making the situation tough for them.
The Sri Ram Sagar Project in Telangana has no irrigation water. As per state water minister, a Rs. 1100 crore work was going on to renovate the dam. Meanwhile farmers of about 24 villages have started protest demanding irrigation water form SRSP for their standing crops. Given the tense situation, the State Govt has deployed heavy police forces to control farmers agitation.
At the same time, farmers in North Gujarat farmers have lost 40% of sown crops particularly in Ahmedabad, Morbi and Surendranagar. Non availability of Narmada waters have added to the problems. It is worth to mention that mismanagement of water during past four months in Narmada dam by the authority, has worsened the plight of farmers. Meanwhile, there are reports of furious Surendranagar farmers themselves opening the dam gates going against authority.
Similarly, lack of rainfall in Beed district which is part of Marathwada in Maharashtra has affected the rural population badly. In fact, the rainfall situation in a fourth of India, including Bihar and Uttar Pradesh, was in stark contrast to the rest of the country. Overall, the southwest monsoon in 2018 was only 2 % below normal by July, 27.
The southwest monsoon in Bihar was almost 40 % below normal till July 27 and the state was set to be formally declared ‘drought-hit’. It is worth to mention that the monsoon scenario seems less than reassuring, based on Skymet latest forecast and reading between the lines of IMD Aug. 3, press release.

About Madhya Pradesh
The state of Madhya Pradesh (MP) was bifurcated in the year 2000. The total area of MP state is 3,08,245 sq. km. The state has been divided into 50 districts and 342 sub districts. The total human population of the state is 725.97 million. (2011 census) with a decadal growth rate of 20.3%. Key centres of growth are around the urban centres of Gwalior, Indore, Bhopal and Jabalpur.
It has a subtropical climate. Hot dry summer extends from April to June followed by monsoon from July to September and winter months (November to February) are cool and relatively dry. The average rainfall is about 1,370 mm and it decreases from east to west. Summer mean maximum temperature rises to about 42.5 deg C in northern parts and the average temperature during winters is as low as 10 Deg C again in the north while it varies from 10 – 15 deg C in the south.

Reliable data and information that is both correct and validated on ground, is a pre requisite to understand any feature or activity. And for a river, a constantly evolving and truly complex entity, it becomes even more crucial. The wellness quotient of rivers, their present health status, all these and more can only be understood, once we have the rudimentary knowledge of the river and the basins that they form.
A step in this direction has been taken up by the India WRIS (Water Resources Information System) project (A joint venture between Central Water Commission and Indian Space Research Organisation), that aims “to provide a ‘Single Window Solution’ for water resources data & information in a standardized national GIS framework”[i]. This project has generated 20 basin level reports that share important information on the salient features of the basin, their division into sub basins, the river systems that flow through it and the water resource structures, such as irrigation & hydro electric projects in the basin. Another crucial inclusion is the length of major rivers in each basin, which have been GIS calculated (Geographic information system)[ii] and in a few reports the place of origin of the rivers too is mentioned. (Ganga Basin Report). This is an improvement over the earlier documented river lengths that included the canal length along with the river lengths, in earlier CWC documents (e.g. water and related statistics)!
The Basin reports include basin level maps which also show the proposed inter basin transfer links and the major water resource structures & projects. Individual maps at the sub basin level mark the rivers & their watersheds. The report gives details on the topography, climate, the land use / land cover area , and also the information on hydro meteorological stations like groundwater observation cells, flood forecasting sites and even water tourism sites.
These reports can be downloaded from the WRIS site.[iii]
The reports are an attempt to document the water resources data & information for a better and more integrated planning, at the basin level. A table below tabulates some important parameters from the 20 basin reports.
Missing Dams! It can be seen from table on next page that total number of dams in all the 20 basins come to 4572. Assuming that this includes all the completed large dams in India by Dec 2013 (WRIS report is dated March 2014), if we look at the number of large dams in India as in Dec 2013 in the National Register of Large Dams (NRLD), the figure is 4845. This leaves a difference of 273 large dams, which are missing from the WRIS list! This seems like a big descripancy. Unfortunately, since NRLD gives only statewise list and does not provide river basin wise list and since WRIS list provides only river basin wise list and does not provide the names of districts and states, it is not possible to check which are the missing dams, but WRIS need to answer that.
Sub Basins These 20 basins have been further delineated into a number of sub basins. The sub basins details include the geographical extent of the sub basin, the rivers flowing in it, the states that they travel through, number and size range of watersheds and also the details of dams, weirs, barrages, anicuts, lifts & power houses, accompanied by maps at this level. The irrigation and hydro electric projects in the area are detailed and mapped for greater convenience. The sub basin list is given here to get a detailed picure.

Narmada Basin: Some details To understand the compiled information at the basin level, we take a look at the one of the basin level reports, the Narmada Basin Report[v] (dated March 2014) as an illustrative example. An overview of the basin area right at the beginning, gives its geographical location, shape, size, topography, climate & population. This basic relevant information is tabulated in a concise table for easy access, as given below:
River information The major river flowing in the basin, the Narmada River (also called Rewa) that flows through the 3 states of Madhya Pradesh, Maharashtra & Gujarat, its length (1333 km) and the length of its 19 major tributaries out of a total of 41 is given, based on GIS calculations. There is also a clear river network map of the Narmada basin that demarcates the 3 sub basins along with the watersheds, and shows the dams / weirs /barrages and the rivers in the basin.
- Narmada Upper Sub-Basin, with 16 watersheds
- Narmada Middle Sub-Basin, having 63 watersheds
- Narmada Lower Sub-Basin, with 71 watersheds
The surface water bodies details include the size (less than 25 ha to more than 2500 ha) and type (Tanks, lakes, reservoirs, abandoned quarries or ponds) of existing bodies. Nearly 91.8% of these are tanks.
Irrigation Projects The water resource projects in the basin are as follows:
- 21 Major Irrigation Projects
- 23 Medium Irrigation Projects
- 1 ERM Project
- 6 Hydro-Electric Projects
Interestingly description is only of the major and medium irrigation projects, information on minor projects is completely absent. An attempt to include the details of minor irrigation projects would have made the report more useful. The reports seem to not understand the significance of the smaller projects and their importance for the people and in the conext of the River Basin too.
Water resource structures The number and type of big manmade structures in the basin is given. These are a total of 277 dams, 2 barrages, 2 weirs and 4 lifts, of which again the major structures are marked on a map, and details given as in table below. Dams are classified on the basis of storage and purpose they are used for, and the dam numbers are available at sub basin level.
The report gives tabulated data for each of the dams, which is supposed to have name of the river, height, length, purpose, year of commissioning, etc. Since GIS is the strength of ISRO, they could have easily given latitude and longitudes of each dam, but they have not. Shockingly, in case of 186 of the dams, name of the river on which it is built is given as ‘Local Nallah’, and in case of 10 they have left the column blank. This means for nearly 71% (196 out of 277) of the dams they do not even know the name of the river they are build on. This is actually an improvement over the performance of CWC. The CWC’s National Register of Large Dams[vi], we just checked, mentions Narmada only 13 times (for 12 dams of Gujarat and 1 dam of Madhya Pradesh).[vii]
It is well known that Narmada Basin is the theatre of India’s longest and most famous anti dam movement, Narmada Bachao Andolan. The movement involves opposition to Sardar Sarovar, Indira Sagar, Omkareshwar, Maheshwar, Jobat dams, among others. Such social aspects should also form part of any river basin report.
Surface water quality There are 19 surface water quality observation sites in the basin, that collect water data and the report spells out , “As compared to the other rivers, the quality of Narmada water is quite good. Even near the point of origin, the quality of river water was in class ‘C’ in the year 2001 while it was in class ‘B’ in earlier years. As was observed for most other rivers, in case of Narmada also, BOD and Total Coliform are critical parameters.” This shows that even in Narmada Basin, water quality is deteriorating. The statement also remains vague in absence of specifics.
Inter basin transfer links Details of the Par-Tapi-Narmada Link, which is a 401 km long gravity canal and its proposal to transfer 1,350 MCM (Million Cubic metre) of water from ‘surplus rivers’ to ‘water deficit’ areas is given, along with a map. How has the conclusion of surplus or deficit been reached? Does the assessment exhaust all the options including rainwater harvesting, watershed development, groundwater recharge, better cropping patterns and methods, demand side management, optimising use of existing infrastructure, etc? Is this is the least cost option? Does the water balance include groundwater? Who all will be affected by this or even how much land area will be affected by this proposal, there is absolutely no talk of this? No answers in the report.
There’s more to a river There is no information in basin reports on the regulating or statutory bodies that have a say in the basin in the report. However, some information on the existing organisations and inter-state agreements at the various basin level is given at another WRIS location.[viii]
The Basin reports for 20 basins are clearly an asset for understanding and analysing water resource situation. However, there is no mention of the numerous ecological, social and environmental services these rivers provide us with. The demographic details of the basin are available, but there is no information on the flora and fauna, who also need and thrive on the river waters. A good navigation tool for water resource information and river management projects at basin level, nevertheless, for a broader and more comprehensive outlook these reports should have included the following essential aspects too:
- River status: The present water quality & pollution level of the major rivers as well as their tributaries
- River governance: The local committees, civil bodies and institutions that play a role in river basin development
- River safety measures: Effect of the existing and planned river management projects on the state of the river, people and society.
- River ecology: Status of biodiversity, and other ecological aspects of the rivers
