Andhra Pradesh Water Resources Information and Management System[i] is truly impressive water information system, possibly not available in any other state or even at national level, at any time in India. The comprehensiveness of the water information system is striking, as it not only includes reservoir water storages of Major and Medium Projects, but also storages in minor projects, minor tanks, water conservation structures (check dams, percolation tanks) but also groundwater and most importantly, soil moisture. These are collected in real time from diverse information sources including on ground measurements, satellite based assessments and also sent via mobile apps from diverse sources. And the information is put out in real time, along with number of analysis. The data are collated and analysed using tools from Vassar Labs, like Machine learning, Artificial Intelligence and big data.

PM Modi inaugurated the first multi-modal terminal on the Ganga river in Varanasi on Nov. 12 under a project aimed at promoting inland waterways as a cheaper and more environment-friendly means of transport. The multi-modal terminals are being built as part of the central government’s Jal Marg Vikas Project that aims to develop the stretch of the river Ganga between Varanasi and Haldia for navigation of large vessels weighing up to 1,500-2,000 tonnes. https://www.ndtv.com/india-news/pm-modi-to-inaugurate-1st-multi-modal-terminal-on-ganga-river-in-varanasi-1944924 (9 Nov. 2018)
Explaining the negative impact of waterways projects on Ganga River, Shripad Dharmadhikary in Hindi report titled जलमार्ग परियोजना बदहाल नदियों पर एक हमला writes that the projects lack public consultation “गंभीर बात है कि जलमार्ग विकास से सबसे ज्यादा प्रभावित होने की सम्भावना स्थानीय जनता को है। इसके बावजूद जलमार्ग के विकास से संबंधित ज्यादातर कामों के आयोजन और क्रियान्वयन के लिए न तो इनकी सलाह ली गई है, और न ही इनके बारे में जनता को जानकारी दी गई है। कुल मिलाकर इन जलमार्गों के सामाजिक और पर्यावरणीय प्रभावों का ठीक से आकलन नहीं हुआ है, ऊपर से इन्हें पर्यावरणीय मंजूरी के दायरे से बाहर रखा गया है और सारी प्रक्रिया में लोगों की सहभागिता का भी पूरा अभाव है। ऐसे में जलमार्गों के रूप में इतना बड़ा हस्तक्षेप हमारी नदियों पर एक और बड़ा हमला है जो पहले से बुरी हालत में हैं। https://www.downtoearth.org.in/hindistory/%E0%A4%A8%E0%A4%A6%E0%A5%80%E0%A4%B9%E0%A4%82%E0%A4%A4%E0%A4%BE-%E0%A4%AA%E0%A5%8D%E0%A4%B0%E0%A4%AF%E0%A4%BE%E0%A4%B8-62034 (5 Nov. 2018)
Even as the rainfall during South West Monsoon of India during June Sept 2018 was 9.4% below normal, a number of HFL (Highest Flood Level) crossing flood events were recorded on CWC’s (Central Water Commission) Flood Forecasting (FF) website[i]. Since CWC’s FF site does not provide archived information or comprehensive list of such events, we are here putting together a list of such events that we had noted during the SW monsoon, for future records and also understanding trends of high floods.

Two environmentalists take a walk along a river and find that they should have brought along the policymakers, planners, engineers and politicians claiming to help it.
When heading out on an adventure, it is standard practice to look at satellite imagery of the area to chart an informed plan of action. However, when we were preparing for our walk along the Ken river, we couldn’t access a reliable map of the watercourse all the way from source to mouth.
We tried tracing the river on a map using satellite data for cues, moving upstream from an established point of identity: Chilla ghat, the confluence of the Ken with the Yamuna in Uttar Pradesh. However, this exercise proved difficult and led us astray multiple times, especially in the upper catchment area. It was only later, when walking along the river, did we realise that this was because almost all of Ken’s tributaries have a larger discharge than the Ken itself. Our virtual search for the Ken’s source kept taking us to the source of its tributaries in nearby hills. Thanks to the walk, we now have an actual and detailed map of the river that we intend to share soon.
2018 becomes fifth year in a row when India’s south west monsoon has been below normal. In the beginning of monsoon season, Indian Meteorological Department (IMD) has forecasted rains to be normal with rainfall equal to 97 percent of the long term average. However at the end of the season the overall rainfall turned out to be 91 percent, with deficit of 9 percent at national level. However, as we see in this overview, the situation as move from national to local figures, is much different, mostly much worse.
According to IMD’s State Rainfall Map (cumulative) dated 30 Sept. 2018, the country received 804.0 mm rains against 887.5 mm of normal average. Thus the south west monsoon 2018 had 9.4 percent below normal rainfall.

EDIT article in SCIENCE magazine by TUSHAR SHAH and others on Ganga: “The quickest, cheapest, and most effective way for Mr. Modi to show a less polluted Ganga by 2019 would be operating dams and barrages in the Ganga basin with the sole objective of augmenting river flows. This would be a start to controlling discharge of untreated sewage and industrial waste, which will take a long time.” http://science.sciencemag.org/content/362/6414/503 (2 Nov. 2018)
DOWN TO EARTH says about Ganga: “the river will continue to run as – and even more – polluted as ever… Till August 31, 2018, only a little more than a quarter of the total number of projects sanctioned under it (Namami Gange) had been completed… according to CPCB’s Water Quality Map, only five out of the 70-odd monitoring stations on the river had water that was fit for drinking; only seven had water that was fit for bathing…”
-“Down To Earth quotes a study report and CPCB data to say that the actual measured discharge of wastewater into the Ganga is 123 per cent higher than what has been estimated…”
-“Numerous hydroelectric projects on the Bhagirathi and Alaknanda have turned the upper stretches of the Ganga into ecological deserts, says the Down To Earth assessment. The baseflow amount of the river has decreased by a huge 56 per cent in 2016, as compared to the 1970s.”
– “about 180 MLD of sludge will be generated in the five Ganga Basin states (Uttarakhand, Uttar Pradesh, Bihar, Jharkhand, West Bengal) when they become ODF. If proper sludge management is not done, this would invariably pollute the Ganga. What should cause further concern is that faecal sludge is a bigger pollutant than sewage – while BOD of sewage is 150-300 mg/litre, that of faecal sludge would be 15,000-30,000 mg/litre.” https://www.cseindia.org/ganga-may-not-flow-clean-in-the-near-future-says-new-analysis-9085 (30 Oct. 2018)
Meanwhile, a new CAG report reveals that almost 26 million litres of untreated sewage still flows into the Ganga every day in Uttarakhand. https://www.downtoearth.org.in/news/water/uttarakhand-has-failed-to-rejuvenate-the-ganga-through-namami-gange-62027 (2 Nov. 2018)
On Oct 29, 2018, another landslide dam blocked the path of Yarlung Tsangpo Dam, reportedly at the same location as the Oct 17,2018 landslide dam[i]. It breached on Oct 31, without any reported major calamity, but these repeated occurrences, twice in two weeks and third time in ten months (if we include Dec 2017[ii] landslides) raises a lot of questions. The silence of government of India institutions about the possible causes or other analysis, including by Central Water Commission, Union Ministry of Water Resources, National Disaster Management Authority or even National Remote Sensing Agency has, as expected, raised questions and speculations in Arunachal Pradesh. Continue reading “Another Landslide Dam on Yarlung Tsangpo raises more questions”
A try-out of the technique to grow paddy without puddling at village Chehlan of Ludhiana has resulted in higher yield in comparison to puddled fields, while saving water in the process. The crop was ready for harvest days before expected time, saving irrigation water otherwise to be used for another fourteen days. This trial was funded and supervised by ATMA, a central govt. scheme under the Union Ministry of Agriculture.
Puddling is a traditional method of flooding paddy fields with running water, whereas in non-puddling technique, ‘ridges and furrows’ are formed in soil to let water store in spaces and let it stay, thus reducing irrigation frequency.
“Not paddy but puddling is the enemy of waters of Punjab. It is wastage of water to puddle fields as most of it just evaporates. We have saved 45-50 per cent of water in non-puddled fields. Our yield has been almost 30 per cent more from fields where crop was not puddled. Also, non-puddled crop matured very early, saving at least ten days of irrigation water,” says Rupinder Singh Chahal (43) who along with his brothers Jasvir Singh (48) and Kulwinder Singh (52) experimented with ‘non-puddling’ technique on four acres this year.
Consider the facts: The 600 feet tall statue of Sardar Patel that the Prime Minister of India will inaugurate on Patel’s Birthday on October 31, 2018 is situated bang in the middle of the Narmada river. To take up such unprecedented construction in the middle of the river would require, at the least, environment clearance, since the construction would have huge impacts on the river. No such clearance was sought or given. It would have required environmental impact assessment, environmental management plan, appraisal, public consultations, monitoring and compliance. NONE OF THIS HAPPENED. Continue reading “Why Sardar may have been uncomfortable with the 600 feet statue”
Himachal Pradesh has received 917.3 mm rainfall during South West Monsoon 2018. The amount is 11 percent higher than normal rainfall category of 825.3 mm. However at district level there is considerable variation in the distribution of rainfall. Out of 12 districts in the state, rainfall departure has been in deficit in three districts namely Chamba, Kinnaur and Lahul & Spiti by 38 percent, 32 percent and 43 per cent respectively. All these three districts are in upper part of Himalaya, the origin of many rivers & where mountains are mostly snow covered.
