    This dataset is maintained by the Central Ground Water Board (CGWB) and provides detailed measurements of changes in groundwater levels from a network of 22,965 observation wells across India. The data, which has been collected four times annually (January, March/April/May, August, and November) since 1969, specifically records the fluctuations in the depth to groundwater over time, offering crucial insights into both seasonal and annual variations.
    a b
    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”.
