The Bangladeshi government is considering a proposal from China on the management and restoration of the Teesta River, the country`s fourth longest river that flows from India. Hasina called on India to immediately sign the Teesta River Water Sharing Agreement during a meeting with Foreign Minister V K Singh. Teesta River, is a 315 km (196 mile) river that flows into the eastern Himalayas, flows through the Indian states of Sikkim and West Bengal through Bangladesh and empties into the Bay of Bengal.  It drains an area of 12,370 km2 (4,780 square miles).  In India, it passes through the Darjeeling district and the cities of Rangpo, Jalpaiguri and Mekhliganj. It flows into the Jamuna River near Fulchhari in Bangladesh. A general view of the Teesta River can be seen on 8 September 2011 in Sevok, about 20 km from Siliguri. Indian Prime Minister Manmohan`s visit to Bangladesh on September 6 was marred by uncertainty surrounding the signing of a Teesta River watershed agreement, after strong reservations by India`s West Bengal premier Mamata Banerjee, reports said. AFP PHOTO/Diptendu DUTTA | Photo: AFP Ainun Nishat, the dean of Bangladeshi river experts, said it was unclear whether the project will be successful or not due to a lack of adequate studies on the river. Again, neither West Bengal nor Bangladesh have any idea that the secret of the disappearance of water during the summer months should be attributed to the inorganic process of killing the river by up to 30 hydroelectric projects (most of which are in Sikkim) in the Teesta section (in service and planned). Although hydropower is considered a “non-consuming” use of water operated as a “run of” stream, water must be stored in the low-flow phases in the “ponds” prior to these projects. My own field observations show that due to the low flow, it takes at least 12 to 15 hours of storage per day before the turbines can run. The Teesta River originates from TsoLamo, India, and flows through the states of Sikkim and West Bengal in India and the Rangpur Division in Bangladesh before flowing into the Brahmaputra River in Chilmari, Bangladesh.
Their total length is 414 km with an average annual flow of 60 billion cubic meters of water (BCM) – approximately the amount of water supported by 24 million Olympic-sized swimming pools. More than 30 million people live in the Teesta Basin and depend on the river for drinking, home use, irrigation, industry and cultural and religious activities. It is fed by streams that form in the mountains of Thangu, Yumthang and Donkha. The river then passes through the city of Rangpo, where the Rangpo River meets and forms the border between Sikkim and West Bengal, up to the Teesta Bazaar. Just before the Teesta Bridge, where the streets of Kalimpong and Darjeeling meet, the river is affected by its main influx, the Rangeet River.  During the monsoon, the Teesta River is ecstatic on the banks; both in size and turbulence. Landslides in this area often block parts of the river at this time of year. After the division, Sikkim remained a protectorate of India until it merged with India as a state in 1975. In the 1950s and 1960s, Indian and Pakistani officials began discussions about thawing and sharing Teesta. At the same time, India and Pakistan were negotiating agreements on the Ganges and indus, which overshadowed the Teesta issue.
After the signing of the Indus Water Treaty in 1960, the two countries focused on negotiations on the Ganges and the teesta issue jumped the ladder. East Pakistan outlined a plan to build a dam on its teesta side, which India rejected. East Pakistan proposed “other rivers” to meet India`s irrigation and other needs, and decided to continue the plan; But it wasn`t until 1990 that a dam was completed on the Teesta In present-day Bangladesh. .
