Ude
Ude belongs to the upper basin of the Uda, a river of the wooded uplands east of Lake Baikal. Known as Üde in Buryat, the river flows west to the Selenga; the Khudan is one of the tributaries that join it along the way. Cold winters lock the waterways in ice, while the surrounding forests and river valleys provide habitat for fish such as taimen, lenok and grayling.
