Climate Conditions of Myanmar
The principal water courses flowing separately in Myanmar comprise five rivers, the Ayeyarwady, Sittaung, Thanlwin, Bago, Bilin and their major tributaries such as Chindwin, Myitttha, Mu, Zawgyi, Panlaung, Samon, Myitnge, Mon, Man Salin, Yaw, Mindon and other rivulets. All rivers, with the exception of Thanlwin are wholly rivers within Myanmar and can be considered nationally owned water assets. Their drainage areas are spread widely over the country and their contributory ratio to the whole country is as follows;

The total area of Myanmar is about (167.2) million acres, with the arable land standing at (45.8) million acres, or (27.4) percent of the country's total land area. The total net sown area in 1994-95 was (22.23) million acres, with the area receiving irrigation facilities at only (4.07) million acres, or (18.31) percent. During 1994-95, the irrigated area of (4.07) million acres, plus the double cropping irrigated area of (0.97) million acres totalled (5.04) million acres, requiring about only (30) million acre-feet or water, and amounting to about only (4) percent of available water resources. With further inclusions of drinking water and other utilities even, it approximated only to (5) percent. There are about (26) million or acres in Myanmar that are feasible for irrigation, and even if their full requirements of water for cropping are met, the demand would come up to only (200) million acre-feet of water, representing about only (25) percent of current potential availability. And it is reckoned that of even further steps are taken to utilize current surplus water resources, with the implementation of numerous irrigation projects, the available water resources would remain inexhaustible.
