178. Concrete Bridge across the Kamenka River 9.28.2014

Concrete Bridge near the source of the Kamenka River at Parachute Street 9.28.2014

Translated from Russian Wikipedia:
The Kamenka River (Река Каменка) flows from Big Suzdal Lake and empties into the Lahti Spill in Saint Petersburg. The name was first mentioned in a tax census book in the 1500's. Swedish charts show the names Kablas-Joki and Kioanaki. It is also found on Russian maps as Koёnka.

The river is 12 km long and is from 2-3 m wide to up to 50-60 m wide. It has a depth of 0.2-2 m and a flow rate of 0.2 m / s. The average discharge is 0.3-0.6 m³ / s of water. The catchment area is 35.5 km ². Over 3 km from the source of the river bed is a ditch with swampy floodplain, extending along the northern border of Novo-Orlovsky forest park. At 7.9 km from the mouth, the river Kamenka is blocked by concrete dam with a spillway with a drop of about 2 m. The dam creates a back pressure and forms an artificial reservoir.

The river is created mainly from surface runoff, predominantly snow. There are more than seven bridge crossings; Orel and New Sacred streets, Parachute Street, two more bridge downstream from Shuvalov's career, as well as the wooden railway bridge north of Shuvalovo station and a narrow-gauge railway bridge to the west of the station.

The river water is used for industrial purposes and as drainage of wastewater. The hygienic classification as to the degree of pollution is moderate (with a pollution index of 1-2).
