CHENAB, one of the "Five rivers" of the Punjab, India (the Greek Acesines). It rises in the snowy Himalayan ranges of Kash mir, enters British territory in the Sialkot district, and flows through the plains of the Punjab, forming the boundary between the Rechna and the Jech Doabs. Finally it joins the Jhelum at Trimmu.
The Chenab colony, resulting from the success of the Lower Chenab canal in irrigating the desert of the Bar, was formed out of the three adjacent districts of Gujranwala, Jhang and Mont gomery in 1892. It lies in the Rechna Doab between the Chenab and Ravi rivers in the north-east of the Jhang district, and includes an irrigated area of over 21 million acres. The principal town is Lyallpur (pop. 1921, 28,136) called after Sir J. Broadwood Lyall, lieutenant-governor of the Punjab. It is now an important trade centre, and gives its name to a district with an area of 3,25o sq.m. and a population (1921) of 979,463. The Lower Chenab canal is now supplied with water from the Jhelum through the Upper Jhelum Canal, and the Chenab water is utilised for the upper Chenab canal. This canal, opened in 1912, which has 173 m. of main canals and distributaries, and irrigates over half a million acres, forms part of the great Triple canals project.
