CHINDWIN, river of Burma, the largest tributary of the Irrawaddy, called Ningthi by the Manipuris. It is formed by the junction of the Tanai, the Tawan and the Taron or Turong, but there is doubt as to which is the main stream. The Tanai rises on the Shwedaung-gyi peak of the Kumon range, 12 m. N. of Mo gaung, and flows due north until it reaches the Hukawng valley, when it turns to the west and meets the Taron or Turong river. The last-named flows into the Hukawng valley from the north. Its sources are in the hills to the south of Sadiya, rising from 10,000 to 11,000 ft. above sea-level. It flows in a general east to west direction as far as its junction with the Loglai. It then turns south and breaks into the Hukawng valley a few miles north of Saraw and meets the Tanai about 1 o m. above Kintaw village. Below the Hukawng valley the Chindwin is interrupted at several places by falls or transverse reefs. At Haksa goods have to be transhipped from large boats to canoes. Not far below this the Uyu river comes in on the left bank at Homalin, and from this point downwards steamers ply for the greater part of the year. The Uyu flows through a well-cultivated valley, and during the rainy season it is navigable for a distance of 150 m. from its mouth by steamers of light draught. Below Kindat, the only considerable affluent of the Chindwin is the Myit-tha, which drains the Chin hills. The Chindwin rises considerably during the rains, but in March and April is so shallow in places that naviga tion is difficult even for small steam launches. Whirlpools, nar rows and sandbanks also cause great trouble. The extreme out lets of the river are 22 m. apart, the interval forming a suc cession of long, low, partially populated islands. The most southerly mouth of the Chindwin is, according to tradition, an artificial channel, cut by one of the kings of Pagan. It was choked up for many centuries, until in 1824 it was opened out by an exceptional flood.
