User:Athsiao9/Nawin river

Na-win.—River in Prome District, Pegu Division, Lower Burma; formed by the junction of two streams, known as the North and South Na-win. The north Na-win rises in the Pegu Yoma range to the north of the Pa-dauk spur, and flows down a narrow rocky valley opening on the plains. From its source to Sin-won village, its course is north-west; thence it runs west and south-west till it joins the South Na-win, a mile south of Myo-ma village. The South Na-win also rises in the Pegu Yomas immediately south of the Pa-dauk spur, which forms the watershed between these two streams up to their union at its south-west extremity. As far as the mouth of the Tin-gyi, a stream draining a long and somewhat bell-shaped valley, and joining the South Na-win near Yat-thit, the river has a south-westerly course, winding down a gorge and fed by mountain torrents. Thence it debouches on the plains, and, after a short north-west course, turns south-west to fall into the Irawadi (Irrawaddy), in lat. 18° 49' 30" N., and long. 95° 18' E., near the town of Prome. The chief affluents of the Na-win, after its junction with the South Na-win, are the Kauk-gway, Law-thaw, and Thit-gyi. In the hot season, nearly all these streams are dry; but during the rains they bring down vast volumes of water, the drainage of an area of about 700 square miles finding its way out by means of the Na-win. These feeders are only navigable by small craft for a short time in the year. The Na-win is now mainly used as a channel for floating down the valuable timber from the forests on the Yoma range.
