Merelka
Merelka is a river of the Argun country, remembered in the settlement of the frontier between the Qing and Russia. The Treaty of Nerchinsk in 1689 made the Argun a boundary and called for Russian settlements near the mouth of the Merelka on its southern bank to be moved north. The river flows from the wooded country east of the Argun, whose waters continue towards the Shilka and the Amur.
