AQUIFER MAPPINGARTIFICIAL REACHARGE STRUCTURESROLE OF CGWB by Vidya Nand Negi (Scientist ‘D’) CENTRAL GROUND WATER BORAD NHR, DHARMSALA
Central Ground Water Board • Consultation with regional offices of CGWB • Decisions with the aquifer maps made available for finalizing the location of the proposed water bodies • Details of design of structures required for ground water recharge specific to regions, under planning consideration • Possible scope of services from Regional Offices, CGWB in preparation of a scientific plan for NRM works
HYDROGEOLOGY • VALLEY FILLS Moderate to High Yield 10 – 30 lps • SIWALIKS (Low to Moderate Yield) 5 – 15 lps • CRYSTALLINES / METAMORPHICS (Low to Moderate Yield) 2 – 10 lps

ASSESSMENT OF DYNAMIC GROUND WATER RESOURCES OF HIMACHAL PRADESH ASSESSMENT UNIT-WISE CATEGORIZATION as on March 2013
ROLE OF CGWB in preparation of Scientific Plan for Natural Resource Management • Major activities being taken up by Central Ground Water Board in Himachal Pradesh State : • Micro and Macro level ground water management studies. • Exploratory drilling under National Aquifer Mapping and Management Programme. • Monitoring of ground water levels and water quality through a network of ground water observation wells, implementation of demonstrative schemes for artificial recharge and rainwater harvesting for recharge augmentation. • Periodic assessment of replenishable ground water resources of the State is carried out by the Board jointly with the I&PH Deptt, Govt. of Himachal Pradesh.
The data generated from various studies taken up by CGWB provide a scientific base for water resource planning by stakeholders. • Short term hydrogeological investigation for feasibility of constructing tube wells. • Technical assistance for constructing Ground water recharge structures in the State. • Impart trainings on different aspects of ground water conservation and its management like Tier-II, Tier III (NGWT & RI) and Block level training under JalKrantiAbhiyan. • Board is engaged in various activities related to regulation of ground water development to ensure long-term sustainability of ground water.
