India heavily depends on groundwater resources, which support over 50% of the irrigated area, facilitated by the installation of nearly 20 million tube wells. To harness river waters and promote groundwater recharge, the country has constructed approximately 5,000 major and medium-sized dams, barrages, and similar structures. [15]
India's irrigation covered crop area was about 22.6 million hectares in 1951, and it increased to a potential of 90 mha at the end of 1995, inclusive of canals and groundwater wells. [31] However, the potential irrigation relies on reliable supply of electricity for water pumps and maintenance, and the net irrigated land has been considerably ...
Map of India based on survey of rivers of India.. The Indian rivers interlinking project is a proposed large-scale civil engineering project that aims to effectively manage water resources in India by linking rivers using a network of reservoirs and canals to enhance irrigation and groundwater recharge and reduce persistent floods in some parts and water shortages in other parts of the country.
India's total renewable water resources are estimated at 1,907.8 km 3 a year. [80] Its annual supply of usable and replenishable groundwater amounts to 350 billion cubic metres. [81] Only 35% of groundwater resources are being utilised. [81] About 44 million tonnes of cargo is moved annually through the country's major rivers and waterways. [63]

Central Ground Water Board (CGWB), created in 1970 under the Ministry of Water Resources of India, for regulation of ground water development to ensure long-term sustainability. It is responsible for "providing scientific inputs for management, exploration, monitoring, assessment, augmentation and regulation of ground water resources of the ...
Map of the major rivers, lakes and reservoirs in India. This is a list of largest reservoirs in India, including all artificial lakes with a capacity greater or equal to 1,000,000 acre-feet (1.2 km 3). In terms of number of dams, India ranks third after China, and USA.
