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.

Monitoring of ground water levels from 729 Hydrograph Network Stations (HNS) were carried out in the year 2019-2020 with an objective to assess ground water regime of phreatic aquifer. The water level monitoring was carried out in the months of May’19, August’19, November’19, and January’20.

Central Ground Water Board, West Central Region, has been issuing Ground Water Year Book annually for Gujarat state by compiling the hydrogeological, hydrochemical and groundwater level data collected from the Groundwater Monitoring Wells established by the Board in Gujarat State.

Ground water being a limited resource requires proper management and judicious use of its storage for meeting out demand on long term basis without putting any adverse impact on its regime.

Most of the area in Himachal Pradesh is hilly, mountainous with few intermontane valley in between them. The traditional ground water structures, which are under observation at present, are open wells mostly located in the valley area.

The Central Ground Water Board, North Western Region, has established 1077 Ground water observation wells in Punjab State and Union Territory of Chandigarh for monitoring water level.

The ground water behavior in the Indian sub-continent is highly complicated due to the occurrence of diversified geological formations with considerable lithological and chronological variations, complex tectonic framework, climatological dissimilarities and various hydrochemical conditions.

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.

The revised master plan for artificial recharge to groundwater has been made for the whole country at the level of district/Block. The plan is macro plan formulated to work out the feasibility of various structures for the different terrain conditions of the country and respective estimated cost.

To depict ground water scenario, water level is monitored during pre monsoon, during monsoon, post monsoon and post irrigation period with reference to spatial behaviour of ground water regime for each monitoring period, pre and post monsoon (seasonal), annual (corresponding period of preceding year) as well as changes with reference to last dec
