Nurchüü

Nurchüü is the Mongolian name of the Nercha, a river flowing through the wooded country east of Lake Baikal. Its long course leads south to the Shilka, a tributary of the Amur. Ice holds the river from October until late April or early May. Near its mouth stands Nerchinsk, where Russian and Qing representatives negotiated a treaty defining their frontier in 1689.
