[4] The old capital of the Ava Kingdom was built between its two branches, Myittha River which it gives off to the west and the eastern stream which retains the name Myitnge before it enters the Irrawaddy.

[3] The famous Shwe Sar Yan Pagoda on its north bank, built in 1053 by the Shan princess Sao Mon Hla on her journey home after wedding and later leaving King Anawrahta (1044–1077) of Bagan in central Burma,[6] holds its annual festival starting just before the full moon of Tabaung (March).

[7] Anawrahta constructed an irrigation system consisting of weirs and canals on the Panlaung and the Zawgyi rivers but found the Myitnge too wild to tame.

[8] Three centuries later Thado Minbya (1364–67) built Ava as his capital at the confluence of Myitnge and Ayeyarwady rivers within easy reach of the rice granary at Kyaukse.

[12] A 790 megawatt hydroelectric power plant called Yeywa Dam Project, with assistance from China, is under way on the Myitnge River 50 km (31 mi) southeast of Mandalay.
