The works on the removal of Taldykol store basin scheduled up to 2016. 21 billion tenge ($113,5 million) was spent in three years.

The Ishim River is the river running through northern Kazakhstan and south-central Russia. It is a left-bank tributary of the Irtysh River.

Then the river goes north through Petropavlovsk city in northern Kazakhstan and the flat Ishim Steppe to the Russian town of Ishim, Abatsk and Vikulovo villages before entering the Irtysh River in Ust-Ishim region.

Its total length is 1,522 miles (2,450 km), and it drains an area of 55,600 square miles (144,000 sq km). Mainly snow fed, it overflows its banks in spring and becomes shallow in summer.
