Voronezh Reserve is situated in the northern part of the Usman Forest, an isolated forest surrounded by steppes in the western outskirts of the lowland plains of the Oka and Don River plains.
The forest was formed on the sandy terraces of the left bank of the Voronezh River.
 The terrain is a rolling plain, flattening east to west.
 Altitudes range from a high of 165–169 m at the watershed of Voronezh-Usmanka and Usmanka-Baygora, to a low of 90 m in the floodplain areas of the Voronezh.
  Only 4 km of the Voronezh itself runs through the reserve; the Usman river is more extensive/  It is a typical forest river connecting a chain of lakes, reaching a width of 60 m and a depth of 3–4 meters.
 The floodplain is low and marshy.
 The territory belongs to the "Levoberezhny pridolinno" terraced area subzone that is typical of the forest-steppe province of the Oka-Don Lowland.
