Rybinsk Reservoir
The whole of the district belongs to the basin of the Rybinsk Reservoir. The rivers in the west of the district drain into the Mogocha, which joins the Melecha outside of the district to form the Osen, a major right tributary of the Mologa. The source of the Mogocha is located within the district. The rivers in the east of the district drain into the Rybinsk Reservoir and its tributaries, including the Sit. Much of the district's territory is covered by forests.
