Splitting
Prior to the 1960s, 108 freshwater rivers emptied into the lake. As of 2003, 85% of the river mouths have dried up, including the lake's largest tributary, the Buha River. In between 1959 and 1982, there had been an annual water level drop of 10 centimeters, which was reversed at a rate of 10 cm/year between 1983 to 1989, but has continued to drop since. The Chinese Academy of Sciences reported in 1998 the lake was again threatened with loss of surface area due to livestock over-grazing, land reclamations and natural causes. Lake surface area has decreased 11.7 percent in the period between 1908 and 2000 . As a result of this, or possibly moving sand dune, higher lake floors were exposed, numerous water bodies were separated from the rest of the main lake around since the 20th century. In the 1960s, the 48.9 square kilometres (18.9 sq mi) Gahai Lake (尕海, pinyin: Gǎhǎi) appeared in the northern part of the lake. During the 1980s, Shadao Lake (沙岛, pinyin: Shādǎo) split out in the northwest covers an area of 19.6 km2 (7.6 sq mi), while the northeastern Haiyan Lake (海晏, pinyin: Hǎiyàn) is 112.5 km2 (43.4 sq mi). Another 96.7 km2 (37.3 sq mi) daughter lake split off in 2004. In addition, the lake has now split into half a dozen more small lakes at the border. The water surface has shrunk by 312 km2 (120 sq mi) over the last three decades.

Famous quotes containing the word splitting:
“Verily, chemistry is not a splitting of hairs when you have got half a dozen raw Irishmen in the laboratory.”
—Henry David Thoreau (1817–1862)
“I had an old axe which nobody claimed, with which by spells in winter days, on the sunny side of the house, I played about the stumps which I had got out of my bean-field. As my driver prophesied when I was plowing, they warmed me twice,—once while I was splitting them, and again when they were on the fire, so that no fuel could give out more heat. As for the axe,... if it was dull, it was at least hung true.”
—Henry David Thoreau (1817–1862)
