Кубенское озеро
The district is elongated from northwest to southeast with Lake Kubenskoye, one of the biggest lakes in Vologda Oblast, forming its northeastern border. The lake is shared between Vologodsky and Ust-Kubensky Districts. Almost all of the district's territory lies in the basin of the Sukhona River. In particular, the rivers in the north lie in the basin of Lake Kubenskoye, the source of the Sukhona, and the southern part is in the basin of the Vologda River, one of the major tributaries of the Sukhona. The Lezha River, another major tributary of the Sukhona, forms the southeastern border of the district, and the Sukhona itself forms the eastern border, upstream from the mouth of the Lezha.
