The Ivanovo Rapids are a roughly two-kilometer stretch of the Neva River between where the Svyatka and Tosna rivers meet it. This section is about 210 meters wide and creates a natural transition zone in the river's flow.

These rapids were a difficult passage for ships until the 1970s when major dredging work began. The dredging made the waterway navigable for the increased traffic of the Volga-Baltic route.

Fishermen come year-round to these rapids to fish in the nutrient-rich waters, continuing traditions that connect them to the river.

Vessels passing through these rapids must maintain radio contact with dispatchers on Channel 5 and should not attempt passage when visibility falls below one kilometer. Checking current water conditions before visiting is wise.

The water temperature here remains constant at around 4 to 5 degrees Celsius throughout the year. These stable conditions support a particular ecosystem adapted to the cold river environment.
