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.

Overview of CWC Flood Monitoring Sites 2018: INDIA
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.

Overview of CWC Flood Forecasting Sites 2018: East India
Central Water Commission is the only agency doing flood forecasting in India.

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, in this article we have given an overview of CWC’s flood forecasting and monitoring sites in East India. It includes state wise list of CWC’s Level Forecast, Inflow Forecast and level monitoring sites in East India. Similar report has been published for North India[II] and North East India[III] and we hope to publish reports covering other regions of India too.

Overview of CWC Flood Forecasting Sites 2018: North India
Flood forecasting is an important activity during monsoon, considering the huge and increasing flood prone area, flood frequency, extent 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, along with available details like rivers, sub basin, river basin, Warning level, Danger Level, High Flood Level, Full Reservoir Level, Maximum Water Level. As we see below, there are many gaps in this basic information for the sites that are part of CWC’s list.

DRP News Bulletin,16 July 2018: Dam Safety Is Needed, Can We Depend On CWC Engineers Alone?
India certainly urgently needs credible measures to achieve both structural and operational safety of dams. As the HINDUSTAN TIMES editorial emphasizes, we need much greater transparency, accountability and participation of independent, non government experts at every level of functioning of Dam Safety mechanism. Current Dam Safety Bill draft falls far short of that. This is also underscored by many of the news we bring in this July 16, 208 issue of DRP News Bulletin.
The Tamil Nadu CAG report, as Indian Express reports, has clearly said that the Chennai floods of Dec 2015 were majorly due to the wrong decision of dam operators to release 29000 cusecs of water for 21 hours, in violation of all safety norms, but no was punished for this wrong decision. The same has always been the case.
The Bulletin also brings the warning from, no less than Chief Minister of Assam to NEEPCO that if NEEPCO, the operator of the 405 MW Ranganadi Dam releases water from the dam without warning and when downstream areas are facing floods, they will have to bear the losses people suffer.

How India Measures Water Storages
Govt and media typically report the status of water storage in India using the CWC’s Weekly Reservoir Storage Bulletin, which contain information about just 91 reservoirs in India. In this article we show that the state websites provide information about huge 3863 reservoirs, which even if not sufficient, is a huge improvement over just 91 reservoirs that CWC bulletin includes. We hope all concerned will try to improve the reservoir storage reporting.
It should be added here that this measures only surface water stored in some of the large reservoirs of India. This excludes large number of big reservoirs, lakhs of smaller reservoirs, groundwater aquifers and soil moisture storage. In spite of these limitations, this provides more accurate picture than just the 91 reservoirs of CWC that everyone in India, including media, govt monitoring and policy makers look at.
