CGWB - Changes in Depth to Water Level

Central Ground Water Board monitors groundwater levels throughout the country on a regional scale, four times in a year during the months of March/April/May, August, November and January. This data is collected under the mode of acquisition “Manual”. For monitoring of ground water level, CGWB has a dedicated network of about 25000 monitoring stations called “National Hydrograph Network Stations (NHNS)”, which comprises open dug wells and purpose-built bore/tube wells for water level monitoring called piezometers. Similarly, CGWB has initiated automatic high frequency monitoring by installing Digital Water Level Recorders (DWLR) with telemetry systems under the National Hydrology Project (NHP). This data is collected under the mode of acquisition “Telemetry”.

Methodology Groundwater levels are systematically and periodically monitored across India. These wells are monitored four times annually specifically in January, March/April/May, August, and November to capture seasonal variations in groundwater levels effectively. Each well is geographically mapped and characterized by its longitude, latitude, basin, and sub-basin attributes.
