Site description The Katta-Kurgan water reservoir is situated to the south of Kattakurgan in a natural depression. Tree and shrub plantations (pistachio, oleaster, acacia, maple and others) cover 2,600 ha along the southern, south-eastern and western banks. The reservoir gets its water from the Kara-darya river, which is a right branch of the Zaravshan river. The reservoir fills in autumn, winter and spring. Water is used for irrigation from May to June. The reservoir freezes for a short time in winter. Emergent vegetation is not developed because of water level fluctuations. The phytoplankton of the reservoir is poor in species composition and numbers.
