It usually has an area of 33.41 km2 (13 sq mi),[11] but it varies widely during and between years. It usually increases from the winter and spring floods and decreases during the summer and autumn. In 2014, it was as small as 11.33 km2 (4 sq mi) and as wide as 91.94 km2 (35 sq mi).[3] In the especially dry year of 2000, it was only 0.51 km2 (0.2 sq mi).[14] An inflow from the north by mineral springs in the playa's northern karst zone contribute a smaller volume of water[2] but its much higher solute concentration greatly affects the lake and its sediments.[15][16] In the area's hyperarid climate, there is generally only 28–40 mm (1–2 in) of annual rainfall but about 3,000 mm (120 in) of annual evaporation.[2] It is never more than about 1 m (3 ft 3 in) deep.[2]
South Hulsan Lake has gained somewhat since the year 2000 as North Hulsan has shrunk in size to ephemeral status; this is thought to be related to the many salt pans constructed in recent years to harvest the lakes' sediment for potash.[14]
