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.Continue reading “Uffrenkhal’s Legacy of Recharge Pits Ensures Water Security”→
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.
RajasthanRainfall 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.

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.
Over 250 residents along with environmentalists, activists and members of civil societies formed a human chain at Elliot’s beach on Oct 28, asking State Govt to protect the wetlands, rivers, environment in Ennore creek area from willful destruction of govt agencies and industries. The human chain was joined by all the walk of society irrespective of age group from kids to senior citizens who were holding placards that explain the sorry state of Ennore Creek. http://www.thenewsminute.com/article/residents-chennai-form-human-chain-save-ennore-creek-70724
The Coastal Resource Centre and members of the Save Ennore campaign organized the human chain to raise awareness in the city ahead of the monsoons about the encroachments in Ennore Creek, a backwater located in Thiruvallur district. Residents from all 52 villages in Ennore, who have witnessed the ecology die a slow death, also joined the rally, hoping that the govt would react.
As per the online petition, ten Lakh Chennai residents are at higher risk of disastrous flooding because Govt of Tamil Nadu has allowed Kamarajar Port to convert 1000 acres of Ennore wetlands into industrial real estate. Chennai has barely recovered from the 2015 floods. Don’t let Chennai get flooded again.
Before, during and after the controversial public hearing of destructive Pancheshwar Dam, held in three districts in Uttarakhand, wide media reports in print, in audio-visual and social media gave a loud and clear message: The public hearings violated all legal and democratic norms, in letter and spirit and were clearly illegal.
The Pancheshwar multipurpose project has generated much controversy in India and in Nepal. Its Environment Public Hearing (EPH) was held on August 9, 11 and 17 at Champawat, Pithoragarh and Almora in Uttarakhand. Held during monsoon season in disaster prone hilly region they have invited sharp criticism from all concerned.
There have been scores of reports by local and national media revealing the significant environmental issues being compromised by concerned authorities. We have compiled some key media reports here to illustrate, how clear is the message from all media that the public hearing, the EIA and the project itself involves so many violations of law and democratic norms. They are clearly unacceptable.

About Uttarakhand Rivers
The water quality of Uttarakhand‘s rivers is basically good, especially in the upper reaches. Downstream of some large settlements and in the lower reaches in the Himalayan foot hills the water quality suffers due to the release of untreated sewage and industrial effluents. But the state‘s ambitious program to build 450 hydro power projects threatens the survival of the river ecosystems and the lives and livelihoods of people who live in these river valleys.
