[1] The Buldyrty belongs to the Ural basin and flows across the Syrym, Karatobe and Shyngyrlau districts.

The Buldyrty begins at the confluence of two small rivers, the Bylkyldagan and Zhosaly, close to Aksuat village.

It heads in a southwestward direction across Shyngyrlau District, forming meanders within a floodplain.

The Buldyrty river flows roughly parallel to the Olenti to the northwest and the Kaldygaity to the southeast.

The Buldyrty has three main tributaries, the Shili on the left, and the Tamdy and the 70 km (43 mi) long Zhympity on the right.
