In recent years, the Helmand River has experienced dramatic declines in water flows. In 2001, the river ran at 98% below its annual average. With declining precipitation, the snowfields that supply the headwaters of the Helmand shrank from 41 000 km2 to 26 000 km2 between 1998 and 2000. With continued withdrawals for irrigated agriculture, Helmand waters failed to reach the Sistan basin altogether in 2001. (UNEP, 2003)
