Fig. 1. Map of the Amudarya River delta in Central Asia. The delta is located in the Republic of Uzbekistan, Turkmenistan, and the Autonomous Republic of Karakalpakstan (Uzbekistan). Water distribution in the delta region is largely determined by the Tyuyamuyun system of single-year reservoirs at the entrance to the delta. Water is diverted into a vast network of irrigation and drainage canals. The lakes in the northern part of the delta are intensively used for fishing.
