The Saryozen (Kazakh: Сарыөзен), also spelled Sary-Uzen (Kazakh: Сары-Өзен; Russian: Сары-Узень), is a river in the Karkaraly District of Karaganda Region and the Zhanasemey District of Abai Region, Kazakhstan.
The area surrounding the Saryozen is a seasonal grazing ground for local cattle.
It has its sources in parallel rivulets flowing from the southern slopes of the Myrzhyk range and a north-flowing watercourse of Akshok mountain, at the eastern sector of the Kazakh Uplands.
[5] The Saryozen flows across a hilly and rugged region of the highland Kazakh steppe.
The river fills in the spring with melted snow and rain, reaching its highest level at the end of April.
