Ground Water Year Book is prepared annually by CGWB depicting changes in ground water regime of the country through different seasons. It is an effort to obtain information on ground water levels through representative monitoring wells. The important attributes of ground water regime monitoring are ground water level.

Ground Water Year Book is the basic data report consisting information regarding the ground water regime, depth to water levels and quality and their variations in space and time compiled and analyzed based on the information generated through field studies.

Monitoring of ground water levels from 768 (745+23) Hydrograph Network Stations (HNS) were carried out in the year 2021-2022 with an objective to assess ground water regime of phreatic aquifer. The water level monitoring was carried out manually in the months of May’19, August’19, November’19, and January’20.

This document is part of a series of guidebooks that address various aspects of monitoring and assessment of freshwater. It describes the main features of groundwater that govern its quantity, availability and chemical quality.

Central Ground Water Board, North Central Region, Bhopal monitors ground water level in the state of Madhya Pradesh through a network of 1482 ground water monitoring dug wells and piezometers, four times in a year in order to bring out the spatial and temporal changes in the ground water regime.

Rivers, lakes, and wetlands cover the landscape of our blue planet, but over 97 percent of the world’s freshwater resources lie beneath the ground. In fact, scientists estimate that there is 100 times as much groundwater on Earth as there is freshwater on its surface.

While groundwater accounts for 99 per cent of all running freshwater on Earth, it is often undervalued, mismanaged, and overexploited, according to this report published by the UNESCO.

Safe and clean water supply for domestic as well as for sustainable supply for irrigation and industrial requirement is toughest challenge due to rapidly declining ground water resources in major part of the state. Monitoring of water level plays important role for effective estimation of ground water resources.

Central Ground Water Board, North Western Region, Chandigarh has established Ground Water Observation Wells (GWOW) in Haryana State for monitoring the water levels.

Ground Water Year Book is based on the information generated through field studies. The data has been analyzed by Officers of Central Ground Water Board, State Unit Office, Delhi and presented in the report.
