From the beginning of May 2021, Uttarakhand has started witnessing excessive rainfall events termed as ‘cloud bursts’. Worryingly the intensity and frequency seems on higher side this time. So far there have been about 24 reported cases of ‘cloud bursts’ in the state but the monitoring, prediction and mitigation efforts are lagging far behind.Continue reading “Uttarakhand: Cloud bursts in May 2021”
In July 2018, the National Green Tribunal appointed a Yamuna Monitoring Panel for Delhi, the term of this panel is over and it has submitted its final report. NGT had also appointed similar committees for Haryana and Uttar Pradesh stretch of Yamuna, but those panels never functioned as actively as did the Delhi panel. We urge NGT to accept the petition now filed by Manoj Mishra to give extension to the Delhi Yamuna Monitoring Committee (DYMC) and direct that this committee will continue to function and monitoring and compliance panel for Yamuna river in Delhi.
There is a lot one can say positively about this committee, but arguably the biggest factors are its activeness, responsiveness and transparency. This can be easily seen visiting its website or its twitter page (https://twitter.com/ngtmcyamuna2). The committee also acted as a bridge between various institutions dealing with Yamuna in Delhi and ensured better coordination. The committee’s work is also evident in the number of reports it has submitted, all available on its website. There is always room for improvement in functioning of any such organisation, but this a lot and there are very few cases where one can say this.
Fed by Dudhatoli forest range, the Ramganga West and Nayaar East and West in Uttarakhand are perennial rivers of immense scenic beauty amid emerging and looming threats. This photo blogs highlights some of the charms and concerns of these non-glacial rivers of the Ganga Basin.
Following large scale illegal mining incidents in Yamuna, Chambal, Ken, Betwa and many other rivers in Uttar Pradesh, the National Green Tribunal (NGT) in past few years has issued significant orders. Towards the end of 2018, the Central Board of Investigation (CBI) had also started inquiry into illegal mining case in Betwa river in Hamirpur district which involved the then Mining Minister Gyatri Prajapati and the district magistrate among others. The raids regarding the issue kept taking place throughout 2019. So far the case has not reached the conclusion.
With the help of available media & other reports SANDRP tracks the illegal sand mining incidents of Uttar Pradesh during past one and half years. The 2018 sand mining overview in UP can be seen here.
Flood forecasting is an important activity during monsoon, considering the huge and increasing flood prone area, flood frequency, intensity 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 in North India, comprising of states of Jammu & Kashmir, Punjab, Haryana, Himachal Pradesh, Uttarakhand, Uttar Pradesh, Delhi and Chandigarh. It includes available details like name of river, sub basin, Warning level (WL), Danger Level (DL), High Flood Level (HFL), Full Reservoir Level (FRL), Maximum Water Level (MWL), as applicable. As we see below, there are many gaps in this basic information for the sites that are part of CWC’s list. A similar zonewise overview of CWC’s sites was compiled in 2018, which can be seen here. Overview of CWC Flood Forecasting Sites 2018: North India. We have brought this updated compilation for 2019 as there are large number of changes as ou can see.
Ramganga (West) River originates from the western part of Dudhatoli reserve forest lying between Thailisain block in Pouri and Gairsain tehsil in Chamoli districts of Uttrakhand state. It is an important tributary of National River Gaga. The total length of the river is about 596 km. For first 200 km the river flows in Uttarakhand state and the remaining length falls in the state of Uttar Pradesh. Before it descends into plains, it is impounded by Kalagarh dam inside Jim Corbett National park.
Inspiring tale of three villages in Thalisain tehsil (Pouri Garhwal district, Uttarakhand) which have been putting in sustained efforts for years in creating recharge pits, plantation and forest protection that has ultimately resulted in revival of water sources and Gadganga a small stream part of East Nayaar River basin.

- 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)

This week there are exemplary and encouraging wetlands revival stories from three metro cities of Chennai, Hyderabad and Delhi. In the first example from Hyderabad, meticulously chosen plant species such as tulsi, aswagandha, citronella and hibiscus have been used to create an artificial island to clean Neknampur Lake. The treatment islands are composed of four layers of which the bamboo base keeps the entire structure afloat. Based on soil-less hydroponics, these floating treatment wetlands absorb excess nitrates, thereby reducing the chemical content of the lake water. Microorganisms present in the wetland break down organic matter while the root systems filter out pollutants and sediments. https://www.thenewsminute.com/article/3500-saplings-floating-islands-help-rejuvenate-hyd-neknampur-lake-75819 (The News Minute, 3 Feb. 2018)
Similarly, Chennai-based Care Earth Trust along with the public works department (PWD) and the civic body has managed to restore three urban lakes. While many of the smaller wetlands have vanished over time, many mid-sized wetlands seem to have shrunk by almost 65 percent. Thanks to their joint effort, invasive hyacinth was removed from the Narayanapuram Lake in Pallikaranai, while sewer lines, which emptied into the Perungalathur Lake, have now been plugged. A detailed restoration proposal has been forwarded to the PWD regarding the Korattur-Madhavaram-Ambattur lakes. https://timesofindia.indiatimes.com/city/chennai/hyacinth-out-sewer-line-plugged-three-water-bodies-restored/articleshow/62748110.cms (The Times of India, 2 Feb. 2018)
Meanwhile, Delhi Jal Board (DJB) has taken up interesting new project of creating an artificial lake in Dwarka. The project will supply water in sub-city and improve ground water level too. DJB has approved Rs. 56 crore for the project which will be completed in next seven months. This would the first model project wherein a lake will be used to augment water supply. The special lake is being created next to the Dwarka water treatment plant (WTP) will have a sand bed to allow maximum percolation of water into the ground. It will have a capacity of 10 million gallons (MGD). The project is expected to add supply of 5-6 million gallons water to Dwarka every day.
