Bridges are essential infrastructure for human and cargo mobility across a river. They have also allowed us stop over and gaze on the beauty of flowing water streams without any risk of getting drowned or getting ourselves drenched in water. More and more bridges are being built on rivers without understating their impacts. There is hardly any debate or discussion on governance and decision making process or minimum distances to be maintained between two bridges or limiting the number of bridges on given stretch, considering what the river can support. This report takes a look at the situation of bridges on river Yamuna and describes few examples how they have been impacting the river eco-system.

Central Water Commission (CWC) monitors water level at several hundred sites in the country during monsoon every year. It publishes this information on its Flood Forecast (FF) website[I]. The website has three ways to get this information: Data Flow Map, List Based Exploration, and Hydrograph view. The Hydrograph view provides information for past 72 hours, supposed to be updated every hour. This is in addition to the list of current forecasts.
The CWC’s FF website had in 2018 monsoon, 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.
