The first blog on just concluded South West Monsoon 2019, gave the national picture and broad picture of month wise, state wise, sub division wise and river wise rainfall. This blog provides some details of rainfall in districts of each of the 36 states and Union Territories (UTs) of India. Continue reading “Monsoon 2019: State wise rainfall”
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.
It’s pretty unusual situation in Bhakra, Pong and Ranjit Sagar dams this summer. These reservoirs on Sutlej, Beas and Ravi rivers respectively, allocated to India under Indo-Pak Indus Waters Treaty, are releasing so much water this summer that a significant part of it is flowing into Pakistan, much against the proclamations of the Government.

Across the country, many government officials were killed while taking action against illegal sand extraction in 2018. So were the lethal attacks on reporters and citizens for exposing illegalities and objecting to illegal mining activities. Many innocent people lost lives in accidents related to illegal sand mining related incidents which could have been avoided. This compilation of sand mining related incidents also highlights how illegal sand mining was damaging the infrastructure providing essential services.
Uttrakhand A 115 years old British era bridge on Tons river in Birpur, Dehradun collapsed on Dec. 28 reportedly due to overloaded sand trucks. Two people were killed in the accident. The single lane bridge was damaged during 2013 floods and opened for public after repair.
Since the beginning of 2019, there have been couple of incidents of hailstorm in Haryana and Punjab. The region has also seen good rainfall in January. The hilly states of Jammu & Kashmir, Himachal Pradesh and Uttrakhand have been repeatedly facing heavy snowfall events gripping the large parts of North India in cold waves.
The initial rains and snowfall were seen usual events and considered as beneficial for rabi crops and water demands. However the unusual hailstorm accompanied by heavy rainfall In January 2019 and again on Feb 7-8, 2019 have caused significant damage to standing crops in large part of Haryana, Punjab and Western parts of Uttar Pradesh.
SANDRP has been preparing and presenting the annual overview of sand mining sector for past three years. The issue of illegal sand mining is growing significantly adversely impacting the rivers and dependent communities. The respective governments are also under pressure to regulate the riverbed mining. There is noticeable increase in court cases and judicial interventions.
This year, we are presenting the overview in a state wise format for some key states where the issues are more intense. We start with Punjab state.
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.
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 Flood sites, information 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, SANDRP has published report of CWC’s Level Forecast, Inflow Forecast and level monitoring sites in 5 zones of North India[ii], North East India[iii], East India[iv], South India[v] and West India[vi]. Through this report, we have presented all the data at one place with links to separate zone wise reports with detailed description.

India’s few remaining Indus river dolphins are confined to one short, beautiful stretch of the Beas. They have a fighting chance at survival only if we ensure a healthy river

A dark shape cleaves the Beas river, leaving a long wake in its trail. From the way it moves, it is neither a human, nor fish, nor even a river dolphin. The shape swims strongly, shrugging off the strong current. It holds its line and makes straight for a sandbar, hauling itself up on a buff-coloured spit.
A black dog, probably feral. It shakes itself free of water and, running across the sand, begins tugging at the beached carcass of a cow. Another bigger dog appears out of nowhere, and the two begin to snarl and gorge, yanking and tearing flesh off the arcing ribs.
River sandbars contain multitudes. I was upstream of Harike, the largest wetland in north India. The critically endangered gharial (Gavialis gangeticus), the fish-eating, long-snouted crocodilian, of which no more than a few hundred survive in the world, bask and nest on these sandbars. Freshwater turtles like the red-crowned roofed turtle (Batagur kachuga) and the Indian narrow-headed soft-shell turtle (Chitra indica), among the most endangered of freshwater species, use sand islands extensively to breed and to bask. Hundreds of thousands of birds — some transient visitors from China and Siberia and Central Asia wintering here, some resident — forage, nest, breed, raise chicks. Many of these creatures have this in common – they are all threatened, to greater or lesser degree.
The sight of predatory, feral dogs in this delicate ecosystem comes with chilling implications. Continue reading “Beas Dolphins: A Flash Of Fin, A Glimmer Of Hope”
