The Neva ( , ; , ) 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 , 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 the city of Saint Petersburg, the three smaller towns of Shlisselburg, Kirovsk and Otradnoye, and dozens of settlements. It is navigable throughout and is part of the Volga–Baltic Waterway and White Sea–Baltic Canal. It is the site of many major historical events, including the Battle of the Neva in 1240 which gave Alexander Nevsky his name, the founding of Saint Petersburg in 1703, and the Siege of Leningrad by the German army during World War II. The river played a vital role in trade between Byzantium and Scandinavia.
It has been postulated the name could derive from Indo-European adjective newā which means new – the river began its flow some time between 2000 Before Christ 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.
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 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.St. Petersburg: Encyclopedia. – Moscow: Russian Political Encyclopedia. 2006;
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 was observed in 1924 and the lowest in 1900 at . The average annual discharge is or 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 is within Saint Petersburg and 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, , less than 5 percent enters the Neva. The average summer water temperature is , and 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 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, 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 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 , Petrogradsky at , Krestovsky at , and Dekabristov at ; others include Zayachy Island, Yelagin and . At the source of 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.
In St. Petersburg, along the Neva, there are many gardens and parks, including the Summer Garden, Field of Mars, Rumyantsev, Smolny Convent, Alexander Gardens, Garden of the Alexander Nevsky Lavra and many others. Историко-географический атлас "Ленинград" Historical. Moscow: GUGK CM USSR, 1977
Because of the rapid flow, cold water and lack of quiet pools and aquatic vegetation the diversity of fish species in Neva is small. Permanent residents include such undemanding to environment species as perch, ruffe and Rutilus. Many fish species are transitory, of which commercial value have European smelt, Coregonus albula and partly Salmonidae. Все о реке Неве: мосты, притоки, наводнения...

Besides flooding as a result of tidal waves, in 1903, 1921 and 1956 floods were caused by the melting of snow.
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 the completion of the expansion of the main sewerage plant.
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 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.Ezhov, V. A.

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 the 20-year-old Prince Alexander Nevsky, 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, 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. В "ПЛЕНУ" У ШВЕДОВ . (In "captivity" of the Swedes, in Russian). Sablino.ru.
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 , was brought from the Summer Garden to Petrogradsky Island. The first permanent bridge across Neva, Blagoveshchensky Bridge, 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 was long.
Every winter from 1895 to 1910, electric 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 a few failures in the top electrical wires. The trams ran at the speed of and could carry 20 passengers per carriage. The carriages were converted from the used . About 900,000 passengers were transported over a regular season between 20 January and 21 March.

A river station 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.
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 long pipeline lies below the river bottom and delivers about 42 million tonnes of oil a year. Transneft has finished laying a tunnel under the Neva . Vsluh.ru (25 August 2008).

Neva is the main source of water (96 percent) of St. Petersburg and its suburbs. From 26 June 2009, St. Petersburg started processing the drinking water with ultraviolet light, abandoning the use of chlorine for disinfection. Технологии очистки . vodokanal.spb.ru (in Russian). The Neva also has developed fishery, both commercial and recreational.
Ladoga Canal, built in the first half of the 18th century, is a water transport route along the shore of Lake Ladoga which 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).
