TheBuyunda (Russian:Буюнда) is a river inMagadan Oblast,Russian Far East. It is a right tributary of theKolyma, with a length of 434 kilometres (270 mi) and adrainage basin of 24,800 square kilometres (9,600 sq mi).[1][2][3]
Together with theSeymchan that flows roughly southwards on the facing bank of the Kolyma basin, the Buyunda forms theSeymchan-Buyunda Depression, which limits theUpper Kolyma Highlands from the east.[2][4]
The name of the Buyunda originated in theEvenki language, meaning "where there are wild deer".[4]
The Buyunda is the seventh longest tributary of the Kolyma. It has its sources in theKilgan Massif and heads roughly northwards across the mountainous area of theMaymandzhin Range. After entering the depression it meanders strongly across a wide and marshyfloodplain, its main channel dividing into branches. Finally the river joins the right bank of theKolyma 1,573 km (977 mi) from its mouth. Its confluence with the Kolyma is 100 km (62 mi) 100 km below theUst-Srednekan Hydroelectric Station.Seymchan settlement and the mouth of riverSeymchan are located further downstream on the facing bank.[2][4]
The river is frozen between late October and late May. The main tributaries of the Buyunda are the Bolshaya Kupka and lower Elgen from the right and the upper Elgen, Talaya, Khurchan and Gerba from the left.[1] There are over 1,550 lakes in the basin of the river.[4]
