Katpagan (kk|Қатпаған) is a salt lake in Amangeldi District, Kostanay Region, Kazakhstan.[1]
The lake is located 52km (32miles) to the south of Amangeldi, the district capital. The area is quite desolate, with few settlements.
Katpagan is an endorheic lake of the Turgay Depression and is part of the Uly-Zhylanshyk river basin. The lake lies at an elevation of 111m (364feet) surrounded by numerous small lakes. The Uly-Zhylanshyk flows about 40km (30miles) to the southwest of the southern shore. Smaller lake Kishi Katpagan lies 3.8km (02.4miles) to the south and Zhaltyrsor 29km (18miles) to the northwest.[1]
Katpagan has a roughly semicircular shape, stretching for over 4km (02miles) in an east–west direction. The lake fills with snow and groundwater. It freezes at the end of November and thaws by the end of March. Katpagan partly dries in the summer, the shores becoming a salt marsh as the water recedes.[2] [3]
Typha and Phragmites reeds grow by the shore of Katpagan. The lake basin is surrounded by steppe vegetation.[3]
