The Kondopoga Bay is deeply carved in the land by glacial process. The upper part of the bay receives about 90% of the waters of the Suna River via the Nigozersky (Kondopozhsky) Canal. The bay also receives waste water, most of which comes from the Kondopoga paper mill.
A city of Kondopoga is by the northern tip of the bay.
The bay has numerous rock islands, the largest being Suisari.
