Lake Kubenskoye
The Principality of Yaroslavl separated from the Grand Duchy of Vladimir-Suzdal when the sons of Konstantin Vsevolodovich divided his lands upon his death. Vsevolod Konstantinovich inherited the lands around Yaroslavl on both banks of the Volga River with its feeders — the Mologa, the Yukhot', the Ikhra, the Sit', the Sheksna and Lake Kubenskoye.
