The Ashchyozek (kk|Ащыөзек, meaning "bitter river"; (ru|Ащыозек), also known as "Gorkaya" (Горькая)[1] in Russian, is a river in the Zhanybek and Kaztal districts of West Kazakhstan Region, Kazakhstan. The river is 258km (160miles) long with a basin area of 7150km2.[2] [3]
The river flows in the northern sector of the Caspian Depression, between the Volga and the Ural. The water is used for irrigation and watering livestock.[3] There is a protected area in the lower reaches of the river.[4]
The Ashchyozek has its origin in a source to the southeast of Borsy village in Zhanibek District, very close to the Kazakhstan–Russia border. The river heads roughly southeastwards all along its course, meandering strongly in its last stretch. Finally it ends in lake Zhalpaksor, close to Aralsor. The valley is not well defined. The river is fed by snow and its waters are fresh in the spring, becoming salty and bitter in the summer, when it breaks up into disconnected pools.[3] [5]
River Ashchyozek has seven tributaries with a total length of 169km (105miles); the main ones are the 91km (57miles) long Sherimbetsai, Tatkensai and Bersharal, all from the right. The Ashchyozek freezes in November and thaws in April.[1] [5] [3]
