Utkina plant, Backwater area in Saint Petersburg, Russia.

Utkina Zavod is a backwater on the right bank of the Neva in Saint Petersburg, cut off from the main channel by a dam. Depths reach 4.7 m in the enclosed part against 12.3 m in the river itself. A long narrow concrete pier on dark pilings runs out into the water, lined with short lamp posts and benches, with a small pale cylindrical beacon at its tip and low white passenger vessels moored alongside.

The backwater was created in the late 19th century as a mooring basin for vessels on the Neva, separated from the main channel by a dam. In June 2008 the vessel STS-1, owned by the company Rosresurs, met with a disaster here; according to the city emergency service it carried 40 tonnes of diesel fuel. The historic district of Utkina Zavod takes its name from the basin.

The name Utkina Zavod comes from the backwater itself, and a common explanation credits a local factory owner and landowner named Utkin. Older evidence points to the Finnish Sorsajoki, "duck river", used in Swedish times for the river Utka. The city district Utkina Zavod is named after the inlet.

The site is accessible via regional roads connecting to Saint Petersburg, though visitors should bring necessary supplies as infrastructure around the backwater remains basic with limited amenities.
