CGWB - Changes in Depth to Water Level

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.
