The basin of Eg and Uur Rivers, is one of Mongolia’s beautiful and untouched places: it is covered by thick forests especially larch forests. Taimen fish inhabit this basin area. The Eg river starts from Khuvsgul Lake, the deepest and freshest lake in Mongolia.
The river is 475 km and the drainage basin is 40454 sq km. The river flows into the Selenge River. The Eg is surrounded by smallish mountains with forests and those mountains are located up to 100-150m close to the river. The river valley is very picturesque.
Apart from Erin and Tarvagatia rivers, the Uur river also flows into the Eg river. The river runs through asp, ebony, wicker and many different fruit bushes. The river is 20- 70m wide until the junction of the Eg and Uur rivers, where it further becomes 100-150 m. There are many rapids because it is a mountain river. The river is mainly fed by lake waters therefore its water volume is relatively stable. The Eg River is covered by 0.8-lm thick ice for 150-190 days in winter. Many historical finds dated back to Bronze Age have been found in the valley.
The Young Uur and Old Uur rivers are the source of the Uur River. It is 331km and the drainage basin of the river is 12300 sq km.
