Delger River

The Delger River is 25-40 meters wide at its source and reaches up to 100 meters wide at its lower part. This clearly indicates how large and significant the river is which joins the Selenge River flows further to join the Angara River, which eventually merges with the Yenisei River, reaching the Arctic Ocean.

This area features numerous lakes formed due to glaciation, permafrost, and its thawing, as well as various large and small rivers and streams that interconnect and flow into each other. These rivers and streams converge in the Lower Tsagaan Lake, situated in the northern part of the Darkhad Hollow, and flow westward through a narrow valley, becoming the source of the Yenisei River.
