Teesta Barrage Project

 

Present Status of Project

 

1. Teesta Barrage Project is one of the largest irrigation projects not only in West Bengal but also in the entire eastern region. It will create 9.22 lakh ha. of irrigation potential in six northern districts of West Bengal and 67.50 MW of hydropower from canal falls. 2. The Project has three different phases and the Project envisages utilisation of potential of the Teesta River in the field of irrigation hydropower generation, navigation and flood moderation. 3. The preliminary activities of 1st Sub-stage of Stage-I of Phase-I was started in the year 1975-76 and the work proper was started from 1976-77. 4. The Irrigation areas in different Sub-stages and stages of Phase – I are indicated below districtwise. 5. The drinking water supply for Siliguri Municipal Areas has been effected from the pond of the Mahananda Barrage – one of the pick up barrages of the Project. 6. The annual irrigation potential of the Project will be 5.27 lakh ha. in the 1st Sub-stage, considering the intensity of irrigation of 154%. The 1st Sub-stage will also generate 67.5 M.W. of hydropower from three canal falls in the Mahananda main canal.

Main components of the Project (1st. Sub-stage of Stage-I of Phase-I) are :

6.1 Teesta Barrage at Oodlabari 6.2 Pick up Barrage on – (a) River Mahananda at Fulbari in Rajganj Block in Jalpaiguri District.

(c) Dauk Nagar Main Canal (80.62 km.) (d) Nagar Tangon Main Canal (30.50 km.) 6.4 Construction of 12 Nos. of Major Cross Drainage structures on main canals including major aqueducts on crossings of rivers like: (1) the Karala, (2) the Neem, (3) the Karotowa, (4) the Sahu, (5) the Jorapani, (6) the Barang, (7) the Mahananda, (8) the Nagar, (9) the Luna, (10) the Kanchan, (11) the Kulik and (12) the Dharala. 6.5 Construction of 27 Nos. of Regulator and Fall structures, including 3 Nos. of Power Falls. 6.6 Construction of 166 Nos. of bridges on main canals including crossings of Railway Lines, National Highway, State Highway and Major District Roads. 6.7 Construction of distributaries, minors, sub-minors and water courses upto 8 ha. blocks covering a length of 4200 kms. (approx.) in an area of 3.42 lakh ha. C.C.A. in the six districts. 6.8 Construction of residential and non-residential buildings, stack-yards, stores and godowns throughout the Project Area. 6.9 Construction of Inspection paths, approach roads and other allied works.
