The water level around Heixiazi Island is expected to submerge the whole land mass of 335-square-km, which has an average altitude of 37 meters above sea level, an official from the flood control and drought relief headquarters in northeast China's Heilongjiang Province said.
China and Russia ended a century-long dispute over the island in 2008, known as Bolshoi Ussuriysky Island in Russia, and held a border redrawing ceremony declaring each side owned half of the landmass, which is located at the confluence of the Heilongjiang River, known as the Amur River in Russia, and the Ussuri River.
A reservoir along the Zeya River in Russian territory, a major tributary of the Heilongjiang River, has discharged floodwater, said the official.
Meanwhile, thanks to the unusually high water levels, Jiamusi Port along the Songhuajiang River, also a tributary of the Heilongjiang River, has become accessible to ships carrying much bigger loads than ever before.
A Russian ship loaded with 3,000 tonnes of timber was able to reach the port today morning, said Xu Yanchun, of Jiamusi City's marine affairs bureau. Previously, such timber loads had to be distributed among smaller ships of 600 tonnes capacity due to the lower water levels.
