Thiruvananthapuram–Shoranur canal


The Thiruvananthapuram - Shoranur canal is a historic canal in India, from Trivandrum to Shoranur. It was one of the most arterial transportation mode in erstwhile Travancore princely state. Most of the trade, commerce and freight traffic in Travancore used to happen through this canal. The canal used to pass through rice bowl of the state, Kuttanad, centre of Coir trade i.e. Alappuzha, centre of Cashew business, Kollam, Changanassery market, strategic Thevally, Kayamkulam etc. and used to connect Thiruvithamkoor with Cochin State and Malabar.

History

The T S canal was commissioned in stages under the three erstwhile states of Travancore, Cochin and Madras between the 18th and 19th century. The portion between Channankara and Thiruvananthapuram was first done to effect through-traffic from Varkala to Thiruvananthapuram. Then, Paravur canal was constructed to link the backwaters of Paravur Lake and Edava Kayal. Quilon canal came next, connecting Paravur Lake and Ashtamudi Kayal. Thus, the waterway route in this region was completed by 1880 to have through movement of goods and passenger traffic between the southern parts of Travancore parts of the state.

Course

The total route length of TS Canal is almost 420 kms. However at present this entire stretch is not completely navigable.
Currently the canal is largely unused because of,
Marginal utilisation is there for tourism and passenger transportation in Kollam, Alappuzha, Kottayam and Kochi at present.
In 2005 National Transportation Planning and Research Centre prepared a Rs. 9.2 Crore project to revive the 60.5 km long Kovalam - Kollam stretch of the canal.
There is huge development planned and undertaken on Kollam - Ponnani stretch of the canal as part of development of National Waterway 3 as part of larger 630 km West Coast Canal Project between Kovalam and Bekal.
There is also renovation happening on Parvathi Puthanaar reach of canal by KWIL and cleaning of Varkala Tunnel's Chilakkoor passage by Government of Kerala. Now, of the 74.18-km waterway from Kovalam to Kollam, only 27.5 km are navigable and 11.3 km partially navigable.
