58-676: The river is a part of the Volga–Baltic Waterway . When the canal was under construction, Lake Matkozero was used to deposit the soil, and it does not exist anymore. The Vytegra is connected with the valley of the Kovzha by Novomariinsky Canal in the south. Close to the mouth, the Onega Canal branches off west to bypass Lake Onega and to connect the Vytegra with the Svir . Upstream of the town of Vytegra,

116-426: A few failures in the top electrical wires. The trams ran at the speed of 20 kilometres per hour (12 mph) and could carry 20 passengers per carriage. The carriages were converted from the used horsecars . About 900,000 passengers were transported over a regular season between 20 January and 21 March. The sparking of contacts at the top wires amused spectators in the night. The first concrete bridge across Neva,

174-512: A length of 74 kilometres (46 mi), and the shortest distance from the source to the mouth is 45 kilometres (28 mi). The river banks are low and steep, on average about 3 to 6 metres (10 to 20 ft) and 2 to 3 metres (7 to 10 ft) at the mouth. There are three sharp turns: the Ivanovskye rapids, at Nevsky Forest Park of the Ust-Slavyanka region (the so-called "Crooked Knee"), and near

232-498: A means of river transport for Saint Petersburg on the Baltic with the Russian hinterland. These would shift heavy loads in all but the depths of winter. The prototype (via) Vyshny Volochyok canal completed by 1709, provided a connection of Saint Petersburg to Lake Ladoga . The name of that town means "upper portage". However, the weather on the lake frequently wrecked the barges leading to

290-484: A much larger flood of 760 centimetres (300 in) was described in 1691. Besides flooding as a result of tidal waves, in 1903, 1921 and 1956 floods were caused by the melting of snow. The Federal Service for Hydrometeorology and Environmental Monitoring of Russia classifies the Neva as a "heavily polluted" river. The main pollutants include copper , zinc , manganese , nitrites and nitrogen . The dirtiest tributaries of

348-463: A year. Near the Ladozhsky Bridge there is an underwater tunnel to host a gas pipeline Nord Stream 1 . The tunnel has a diameter of 2 metres (6.6 ft) and a length of 750 metres (2,460 ft) and is laid at a maximum depth of 25 metres (82 ft). Neva is the main source of water (96 percent) of St. Petersburg and its suburbs. From 26 June 2009, St. Petersburg started processing

406-500: Is 0.3 to 0.4 metres (1.0 to 1.3 ft) within Saint Petersburg and 0.5 to 0.6 metres (1.6 to 2.0 ft) in other areas. Ice congestion may form in winter in the upper reaches of the river, this sometimes causes upstream floods. Of the total ice volume of Lake Ladoga, 10.6 cubic kilometres (2.5 cu mi), less than 5 percent enters the Neva. The average summer water temperature is 17 to 20 °C (63 to 68 °F), and

464-729: Is a river in northwestern Russia flowing from Lake Ladoga through the western part of Leningrad Oblast (historical region of Ingria ) to the Neva Bay of the Gulf of Finland . Despite its modest length of 74 kilometres (46 mi), it is the fourth-largest river in Europe in terms of average discharge (after the Volga , the Danube and the Rhine ). The Neva is the only river flowing from Lake Ladoga. It flows through

522-552: Is connecting the River Volkhov and Neva. Some of its historical structures are preserved, such as a four-chamber granite sluice (1836) and a bridge (1832). On 21 August 1963, a Soviet twinjet Tu-124 airliner performed an emergency water landing on the Neva near the Finland Railway Bridge . The plane took off from Tallinn -Ülemiste Airport ( TLL ) at 08:55 on 21 August 1963 with 45 passengers and seven crew on board and

580-478: Is reached above the Liteyny Bridge , and the minimum of 4.0 to 4.5 metres (13 to 15 ft) is in Ivanovskye rapids. In the Neva basin, rainfall greatly exceeds evaporation; the latter accounts for only 37.7 percent of the water consumption from the Neva and the remaining 62.3 percent is water runoff. Since 1859, the largest volume of 116 cubic kilometres (28  cu mi ) was observed in 1924 and

638-513: The Hermitage Bridge . From 1727 to 1916, the temporary Isaakievsky pontoon bridge was early constructed between the modern Saint Isaac's Square and Vasilievsky Island . A similar, but much longer Trinity pontoon bridge, which spanned 500 metres (1,600 ft), was brought from the Summer Garden to Petrogradsky Island . The first permanent bridge across Neva, Blagoveshchensky Bridge ,

696-678: The Littorina Sea , the level of which was 7 to 9 metres (23 to 30 ft) higher than its successor the Baltic Sea. Then, the Tosna was flowing in the modern lower half of the Neva as today, into the Litorinal Sea. In the north of the Karelian Isthmus , the sea was united by a wide strait with Lake Ladoga . The Mga then flowed to the east, into Lake Ladoga, near the modern source of the Neva. Thus

754-827: The Mariinsk Canal System ([Мариинская водная система] Error: {{Lang}}: invalid parameter: |translit= ( help ) ), is a series of canals and rivers in Russia which link the Volga with the Baltic Sea via the Neva . Like the Volga–Don Canal , it connects the biggest lake on Earth, the Caspian Sea , to the World Ocean . Its overall length between Cherepovets and Lake Onega is 368 kilometres (229 mi). Originally constructed in

812-622: The Sheksna River . It then passed Lake Beloye (and Belozersky bypass canal ), Kovzha , its artificial Novomariinsky Canal , the Vytegra to pass through Lake Onega . To or from there vessels sailed through the Onega Canal , the Svir , the Ladoga Canal , and the Neva to or from the Gulf of Finland . In 1829, the Northern Dvina Canal was opened running to the north-east; it connects

870-702: The Siege of Leningrad by the German army during World War II . The river played a vital role in trade between Byzantium and Scandinavia . The earliest people in recorded history known to have inhabited the area are the Finnic people . The word Neva is widespread in Finnic languages , having quite cognate meanings. In Finnish it means poor fen , in Karelian : watercourse and in Estonian (as nõva ): waterway. It has been postulated

928-505: The Smolny Institute , below the mouth of the river Okhta . The river declines 4.27 metres (14.0 ft) in elevation between source and mouth. At one point the river crosses a moraine ridge and forms the Ivanovskye rapids. There, at the beginning of the rapids, is the narrowest part of the river: 210 metres (690 ft). The average flow rate in the rapids is about 0.8–1.1 metres per second (2.6–3.6 ft/s). The average width along

986-554: The Volodarsky Bridge , was built in 1936. During World War II, from 8 September 1941 to 27 January 1944, Leningrad was in the devastating German Siege . On 30 August 1941, the German army captured Mga and came to Neva. On 8 September Germans captured Shlisselburg and cut all land communications and waterways to St. Petersburg (then Leningrad). The siege was partly relieved in January 1943, and ended on 27 January 1944. A river station

1044-722: The Vytegorsky Reservoir was filled. The whole river basin of the Vychegda is located in the central part of Vytegorsky District. The valley of the Vytegra is populated, in particular, the town of Vytegra is located on both banks of the river. The names of both Vytegra and Vytegorsky District originates from the name of the river.

1102-508: The 20-year-old Prince Alexander Yaroslavich , aimed to stop the planned Swedish invasion. The Swedish army was defeated; the prince showed personal courage in combat and received the honorary name of "Nevsky". As a result of the Russian defeat in the Ingrian War of 1610–17 and the concomitant Treaty of Stolbovo , the area of the Neva River became part of Swedish Ingria . Beginning in 1642,

1160-585: The 8th to 13th centuries, Neva provided a waterway from Scandinavia to the Byzantine Empire . In the 9th century, the area belonged to Veliky Novgorod . The Neva was already mentioned in the Life of Alexander Nevsky (13th century). At that time, Veliky Novgorod was engaged in nearly constant wars with Sweden. A major battle occurred on 15 July 1240 at the confluence of the Izhora and Neva Rivers. The Russian army, led by

1218-509: The Church of the Intercession. Raised in 2007, it is a wooden replica of a historical church which stood on the southern shore of Lake Onega. That church was constructed in 1708 and it burned down in 1963. It is believed to be the forerunner of the famous Kizhi Pogost . Old Ladoga Canal , built in the first half of the 18th century, is a water transport route along the shore of Lake Ladoga which

1276-596: The Leningrad Oblast. They include the fortress Oreshek , which was built in 1323 on the Orekhovy Island at the source of Neva River, south-west of the Petrokrepost Bay, near the city of Shlisselburg . The waterfront of Schlisselburg has a monument of Peter I. In the city, there are Blagoveshchensky Cathedral (1764–95) and a still functioning Orthodox church of St. Nicholas, built in 1739. On the river bank stands

1334-701: The Maritime Board ( Morskaya Kollegiya ) of the Russian government, 17.6 million tons of cargo were carried over the Volga–Baltic Waterway in 2004, close to its maximum capacity. The Lower Svir Lock was one of the two busiest locks on Russia's inland waterways (the other one was the Kochetov Lock on the lower Don River ).

1392-681: The Mga then was separate from the Tosna/lower-Neva basin. Near the modern Lake Ladoga, by glacial rebound land rose faster, and an endorheic lake briefly formed. This overspilled, eventually the whole Mga valley and thus broke into the western valley (the valley of the Tosna/lower-Neva). The Ivanovo rapids of the modern Neva were created at the breakthrough. According to early books, the breakthrough may have been about 2000 BC, but according to more recent research, this happened at 1410–1250 BC, making

1450-553: The Neva River runs from late April to November. To the west of Shlisselburg, an oil pipeline runs under the river. The pipeline is part of the Baltic Pipeline System , which provides oil from Timan-Pechora plate, West Siberia , Ural , Kazakhstan and Primorsk to the Gulf of Finland. The 774-metre (2,539 ft) long pipeline lies 7 to 9 metres (23 to 30 ft) below the river bottom and delivers about 42 million tonnes of oil

1508-455: The Neva are the Mga, Slavyanka, Ohta, and Chernaya. Hundreds of factories pour wastewater into the Neva within St. Petersburg, and petroleum is regularly transported along the river. The annual influx of pollutants is 80,000 tonnes, and the heaviest polluters are Power-and-heating Plant 2 ( Russian : ТЭЦ-2 ), "Plastpolymer" and " Obukhov State Plant ". The biggest polluters in the Leningrad Oblast are

1566-441: The Neva, near Shlisselburg, there are the two small islands of Orekhovy and Fabrichny. Island Glavryba lies up the river, above the town of Otradnoye . There is almost no aquatic vegetation in Neva. The river banks mostly consist of sand, podsol , gleysols , peat , and boggy peat soils. Several centuries ago, the whole territory of the Neva lowland was covered by pine and spruce mossy forests. They were gradually reduced by

1624-700: The ambitious project of the Ladoga Canals into the southern coast of the lake. Under Alexander I of Russia , the waterway through Vychny Volochyok was complemented by the Tikhvin canal system (1811) and the Mariinsk canal system (1810), the latter becoming by far the most popular of the three. The Mariinsk was an outstanding monument of early 19th-century hydrotechnics , which proved to be key to national economic prowess. The system started in Rybinsk and passed through much of

1682-606: The capital of Ingria was Nyen, a city near the Nyenschantz fortress. Because of financial and religious oppression, much of the Orthodox population left the Neva region, emptying 60 percent of the villages by 1620. The abandoned areas became populated by people from the Karelian Isthmus and Savonia . As a result of the Great Northern War of 1700–21, the valley of Neva River became part of Russian Empire . On 16 May 1703,

1740-582: The cities of Shlisselburg, Kirovsk and Otradnoye, as well as the Kirov thermal power station . More than 40 oil spills are registered on the river every year. In 2008, the Federal Service of St. Petersburg announced that no beach of the Neva was fit for swimming. Cleaning of wastewater in Saint Petersburg started in 1979; by 1997, about 74% was purified. This rose to 85% in 2005, to 91.7% by 2008, and Feliks Karamzinov expected it to reach almost 100% by 2011 with

1856-565: The city of St. Petersburg was founded in the mouth of Neva and became capital of Russia in 1712. Neva became the central part of the city. It was cleaned, intersected with canals and enclosed with embankments. In 1715, construction began of the first wooden embankment between the Admiralty building and the Summer Garden . In the early 1760s works started to cover it in granite and to build bridges across Neva and its canals and tributaries, such as

1914-585: The completion of the expansion of the main sewerage plant. Many sites of ancient people, up to nine thousand years old, were found within the territory of the Neva basin. It is believed that around twelve thousand years BC, Finnic people ( Votes and Izhorians ) moved to this area from the Ural Mountains . In the 8th and 9th centuries AD, the area was inhabited by the East Slavs who were mainly engaged in slash and burn agriculture, hunting and fishing. From

1972-584: The delta of Neva consisted of 48 rivers and canals and 101 islands. The most significant distributaries of the delta are listed in the table. Before construction of the Obvodny Canal , the left tributary of that area was the Volkovka; its part at the confluence is now called Monastyrka. The Ladoga Canal starts at the root of Neva and connects it along the southern coast of Lake Ladoga with the Volkhov . Some canals of

2030-405: The delta were filled over time, so that only 42 islands remained by 1972, all within the city limits of St. Petersburg. The largest islands are Vasilyevsky at 1,050 hectares (2,600 acres), Petrogradsky at 570 hectares (1,400 acres), Krestovsky at 420 hectares (1,000 acres), and Dekabristov at 410 hectares (1,000 acres); others include Zayachy , Yelagin and Kamenny Islands . At the source of

Leningrad Oblast : St. Petersburg: St. Petersburg, Neva delta Construction of the Novo-Admiralteisky Bridge , a movable drawbridge across the river, has been approved, but will not commence before 2011. Whereas most tourist attractions of Neva are located within St. Petersburg, there are several historical places upstream, in

2204-533: The early 19th century, the system was rebuilt for larger vessels in the 1960s, becoming a part of the Unified Deep Water System of European Russia . The original name "Mariinsky" is the credit to Empress Maria Feodorovna , the second wife of Emperor Paul I of Russia . After Peter the Great wrested the southern and southeastern shore of the Gulf of Finland from Sweden, it made for a great city to secure

2262-556: The fires and cutting for technical needs. Extensive damage was caused during World War II : in Saint Petersburg, the forests were reduced completely, and in the upper reaches down to 40 to 50 percent. Forest were replanted after the war with spruce, pine, cedar , Siberian larch , oak , Norway maple , elm , America, ash , apple tree, mountain ash and other species. The shrubs include barberry , lilac , jasmine , hazel , honeysuckle , hawthorn , rose hip , viburnum , juniper , elder , shadbush and many others. Nowadays,

2320-729: The late 19th century to park unused ships. Neva is part of the major Volga–Baltic Waterway and White Sea – Baltic Canal , however it has relatively low transport capacity because of its width, depth and bridges. Neva is available for vessels with capacity below 5,000 tonnes. Major transported goods include timber from Arkhangelsk and Vologda ; apatite , granite and diabase from Kola Peninsula ; cast iron and steel from Cherepovets ; coal from Donetsk and Kuznetsk ; pyrite from Ural; potassium chloride from Solikamsk ; oil from Volga region. There are also many passenger routes to Moscow , Astrakhan , Rostov , Perm , Nizhny Novgorod , Valaam and other destinations. Navigation season on

2378-406: The left, and Okhta and Chyornaya Rechka on the right side of Neva. The hydrological network had been altered by the development of Saint Petersburg through its entire history. When it was founded in 1703, the area was low and swampy and required construction of canals and ponds for drainage. The earth excavated during their construction was used to raise the city. At the end of the 19th century,

2436-504: The lower Sheksna (one of the Volga's tributaries) through Kubenskoye Lake to a canalised Northern Dvina , flowing into the White Sea . The system was further expanded: three more canals, Belozersky, Onezhsky, and Novoladozhsky, enabling smaller craft to bypass dangerous waters of the three big lakes (Beloye, Onega and Ladoga), were inaugurated towards the end of the century. Another connection

2494-450: The lowest in 1900 at 40.2 cubic kilometres (9.6 cu mi). The average annual discharge is 78.9 cubic kilometres (18.9 cu mi) or 2,500 cubic metres per second (88,000 cu ft/s) on average. Due to the uniform water flow from Lake Ladoga to the Neva over the whole year, there are almost no floods and corresponding water rise in the spring. The Neva freezes throughout from early December to early April. The ice thickness

2552-522: The name could derive from Indo-European adjective newā which means new – the river began its flow some time between 2000 BC and 1250 BC. However, the local place names with such influence coincide with Scandinavian traders and Slavs' first main settlement in the region, in the 8th century AD. In the Paleozoic , 300–400 million years ago, all the delta region was covered by a sea. Modern relief, eminences, were formed by glacial scouring. Its retreat formed

2610-557: The new Volga–Baltic Waterway was opened on 5 June 1964. 39 old wooden locks were replaced with 7 new locks, and one parallel lock was built later in 1995. The locks' limiting dimensions are 210 m long, 17.6 m wide and 4.2 m deep, allowing passage of river-sea ships of up to 5000 tons displacement. Such ships were able to sail directly across the big lakes instead of using the bypass canals. Typical travel: Cherepovets to/from Saint Petersburg fell to 2.5–3 days, from 10–15. The modern route sometimes follows

2668-405: The river is 400 to 600 metres (1,300 to 2,000 ft). The widest places, at 1,000 to 1,250 metres (3,280 to 4,100 ft), are in the delta, near the gates of the marine trading port, at the end of the Ivanovskye rapids near the confluence of the river Tosna, and near the island Fabrinchny near the source. The average depth is 8 to 11 metres (26 to 36 ft); the maximum of 24 metres (79 ft)

2726-423: The river rather young. The valley is lined with glacial and post-glacial sediments and has changed little over 2,500 years. The delta was formed at that time, technically a pseudodelta, as not from accumulation of river material but by scouring past sediments. The Neva flows out of Lake Ladoga near Shlisselburg , flows through Neva's lowlands and discharges into the Baltic Sea in the Gulf of Finland . It has

2784-423: The route of the old Mariinsk system and sometimes diverges from it. Six of the canal's eight locks are along 35 km of the northern slope, descending 80 metres. Only 2 locks (which are parallel) are on the southern slope, for a rise of 13 metres, near Sheksna on the Sheksna River , 50 km upstream from Cherepovets . The canal route on the northern slope follows the Vytegra flooded riverbed. Thus

2842-562: The summit pound of the canal between Pakhomovo locks on Vytegra and Sheksna Reservoir dam is 278 km. It comprises an artificial canal (40 km long), much of the Kovzha , Lake Beloye , and part of the Sheksna . The route of the southern slope follows the Shekshna , where it parallels the Rybinsk Reservoir . The canal is used for oil and lumber export and for tourism. According to

2900-514: The swimming season lasts only about 1.5 months. The water is fresh, with medium turbidity; the average salinity is 61.3 mg/L and the calcium bicarbonate content is 7 mg/L. The basin area of Neva is 5,000 km , including the pools of Lake Ladoga and Onega (281,000 km ). The basin contains 26,300 lakes and has a complex hydrological network of more than 48,300 rivers, however only 26 flow directly into Neva. The main tributaries are Mga , Tosna , Izhora , Slavyanka and Murzinka on

2958-518: The upper regions of the river are dominated by birch and pine-birch grass-shrub forests and in the middle regions there are swampy pine forests. In St. Petersburg, along the Neva, there are many gardens and parks, including the Summer Garden , Field of Mars , Rumyantsev, Smolny , Alexander Gardens , Garden of the Alexander Nevsky Lavra and many others. Because of the rapid flow, cold water and lack of quiet pools and aquatic vegetation

Every winter from 1895 to 1910, electric tramways were laid on the ice of the river, connecting the Senate Square , Vasilievsky island , Palace Embankment and other parts of the city. The power was supplied through the rails and a top cable supported by wooden piles frozen into the ice. The service was highly successful and ran without major accidents except for

3132-497: Was added in the 1930s, when the infamous White Sea – Baltic Canal was constructed by gulag prisoners at enormous human cost between Lake Onega and the White Sea . Since the 1990s the Volga–Baltic Waterway has grown as a tour boat route to sail and/or motor along or around the Golden Ring of Russia . In 2016, the core of Astravets Nuclear Power Plant , VVER-1200 , which was 330 tonnes, 13 meters high, and 4.5 meters in diameter,

3190-631: Was built above the Volodarsky Bridge in 1970 which could accept 10 large ships at a time. Wastewater treatment plants were built in Krasnoselsk in 1978, on the Belyi Island in 1979–83, and in Olgino in 1987–94. The South-West Wastewater Treatment Plant was constructed in 2003–05. Neva has very few shoals and its banks are steep, making the river suited for navigation. Utkino Backwaters were constructed in

3248-408: Was opened in 1850, and the second, Liteyny Bridge , came into operation in 1879. In 1858, a "Joint-stock company St. Petersburg water supply" was established, which built the first water supply network in the city. A two-stage water purification station was constructed in 1911. The development of the sewerage system began only in 1920, after the October Revolution , and by 1941, the sewerage network

3306-441: Was scheduled to land at Moscow -Vnukovo ( VKO ). After liftoff, the crew noticed that the nose gear undercarriage did not retract, and the ground control diverted the flight to Leningrad ( LED ) because of fog at Tallinn. While circling above St. Petersburg at the altitude of 1,650 feet (500 m), under unclear circumstances (lack of fuel was one of the factors), both engines stalled. The crew performed an emergency landing on

3364-408: Was transferred to the plant via the Tsimlyansk Reservoir , the Volga–Don Canal , the Volga–Baltic Waterway, the Volkhov River and a special rail car . In Soviet times, the Mariinsk canal system was constantly improved. Two locks were built on the Svir River (in 1936 and 1952); 3 locks were built on the Sheksna River . Major improvement of the Volga–Baltic Waterway took place in 1960–1964, and
