==Geography==
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.{{cite web|url=https://maps.vlasenko.net/smtm1000/m-39.jpg|title=M-39 Topographic Chart (in Russian)|access-date=15 November 2024}}
