Rybinsk Reservoir
The whole area of the district is flatland adjacent from the west to the Rybinsk Reservoir, which was filled in the 1940s and submerged the lower course of the Mologa River, a major tributary of the Volga River. The Mologa forms the northeastern border of the district, and rivers in the whole area in the district drain into the Mologa or formerly drained into the Mologa and now drain into the Rybinsk Revservoir. The largest tributaries of the Rybinsk Reservoir within the district are the Renya (with the left tributary, the Zvana), the Kesma, and the Sebla. Much of the area of the district is covered by forest.
