In AstanaEdit
According to the President of Kazakhstan, Nursultan Nazarbayev, Astana was chosen as the capital in part due to the presence of the river. The city is also divided into two sections, the Right (northern) Bank of the Ishim or the old town, and the Left (southern) Bank, where the new government buildings such as the Ak Orda, the House of the Government, and the Supreme Court are located, as well as many prestigious apartment and living complexes.
Since 1998, the Ishim in Astana has been actively managed, for flood management and maintaining water level, in order to provide for recreational use and ensure the showpiece appearance. It is dammed downstream of central Astana, keeping its level higher than it otherwise would be most of the time, while the river bottom has been made deeper, in order to let flood waters through faster. In central Astana, near the city park, there is now a public beach and pedalo boat rental; meanwhile, if the river had not been dammed, "citizens would have been able to walk across it".<ref name="astana">Реки, каналы, мосты, набережные Template:Webarchive (Rivers, Canals, Bridges, Embankments).

The city authorities also have plans for further deepening the river, which will eventually allow small passenger boats to operate on a Template:Convert section of the river through the nation's capital.<ref name="navi"/>
To maintain the desired level of water flow, water is pumped to the Ishim from the Irtysh, over the Irtysh–Karaganda Canal and a pipeline.
