Central water commission provides time series data of Rainfall, Reservoir Level, reservoir live storage, River Level & Flow and Surface Water Quality (on monthly basis for 66 parameters of 441 water quality stations). In addition to time series data, CWC along with state water resources departments provided data on country’s Water Resources Projects (irrigation infrastructure and command areas). The data is now available for editing by State WRDs through Online Web Editor module. CWC monitors the monthly water spread area of Snow Glacial lakes and water bodies from June to October based on satellite imageries. The data is available for a period of 2009-2019. Static data on Reservoir Sedimentation Studies regarding loss of storage capacity due to sedimentation is also provided by CWC under Sedimentation capacity survey. Command area-based assessment of Waterlogging and Soil Salinity is also provided by CWC in the current version of web-portal. (http://www.cwc.gov.in/)
