Water Data
Surface Water

The surface-water resources of a nation are the water in the rivers, streams, creeks, lakes, wetlands and reservoirs which is vitally important to our everyday life. It is an important source of drinking water and is used for the irrigation, industrial and as well as other public uses. The availability of surface water varies depending upon the precipitation, storage capacity (lakes, wetlands and artificial reservoirs), permeability of the soil, runoff characteristics of the land, timing of precipitation and the local evaporation rates etc.

Information of surface water and availability in a single platform is a prerequisite for resources planning. India-WRIS web portal collects data regarding surface water from varied sources, stores and manages the data and also make it available to download in a report format for easy access to users. This information is also used for derived information in Water Audit module

The modules containing surface water data are:

  • Reservoir level: The information of the amount of water (Average Current Storage in BCM) stored in reservoirs across the country, based on data from different sources. 
  • Reservoir Sediment Study: This module provides information of capacity loss of reservoirs due to silt deposition. It offers the result of sediment study done using remote sensing technique and hydrographic survey of some selected reservoirs spread across the country. Data of the catchment area of the reservoir, design rate of sedimentation, initial capacity & reservoir levels in different years etc. of those selected reservoirs are provided in this module.
  • Surface Water Bodies: It offers the visualization of mapped water bodies with associated information categorized under different area classes at administrative (National/State/District) and hydrological unit-wise (Basin/ Sub-basin).
  • Rivers points (hydro-observation stations) data: Information of the hydro-observations sites live daily water level and river flow time series data is available in this module.
  • River Information: The module shows river systems of the country with its associated attributes such as river name, length, origin, order, etc.

The glacial lakes/water bodies have been mapped based on the visual interpretation of AWiFS satellite images. The water-spread areas of glacial lakes and water-bodies (>50 hectares) from 2011 to 2021 (June to October) and the change in the WSA (base year 2009) is presented as per the joint study of CWC & NRSC.

Ground water

Groundwater, water that occurs below the surface of Earth, where it occupies all or part of the void spaces in soils or geologic strata. It is also called subsurface water to distinguish it from surface water.

Groundwater is a secure source of supply and has always been used by most of the economic activities, particularly for urban supply and industrial use. As farmers invest in individual water supply, groundwater becomes a preferred resource option.

Understanding and managing groundwater resources requires the integration of large amounts of high-quality data from different sources. India-WRIS platform serves the purpose of data collection, storage and dissemination of ground water resources through an integrated approach. This data on ground water is also used for derived information in Water Audit module.

The data is sub-categorized into State-District-Station wise level report, Seasonal –Yearly – Monthly - Daily Fluctuation, and trends of water level. The live data is updated via telemetry stations. Data is accessed and made available in an integrated approach with WIMS.
  • Ground Water Quality: Data on quality of ground water assessed with 85 parameters and is available on monthly and yearly basis for a period of May-2000 to till date.
  • Ground Water Resource Estimation: Data shows the estimates of dynamic ground water resources in terms of annual replenishable ground water resources (recharge), annual ground water draft (utilization) and the percentage of utilization with respect to recharge (stage of development). The assessment units (blocks/watersheds/mandals/firkas) are categorized as Over Exploited, Critical, semi critical, Safe based on Stage of Ground Water Development (Utilization) and the long-term water level trend (generally for the period of 10 years).
