68-715: The district is the only one in St. Petersburg to lie on both banks of the Neva River . It borders with Krasnogvardeysky and Tsentralny Districts in the north, Vsevolozhsky District of Leningrad Oblast in the east, Kolpinsky District in the southeast, and with Frunzensky District in the west. The district was established in 1917. Nevsky District comprises the following nine municipal okrugs : Neva River The Neva ( / ˈ n iː v ə / NEE -və , UK also / ˈ n eɪ v ə / NAY -və ; Russian : Нева́ , IPA: [nʲɪˈva] )

136-426: 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,

204-512: 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

272-484: 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

340-646: A number of other Salmonidae as well as, albeit rarely, endangered Atlantic sturgeon (formerly confused with European sea sturgeon ). Commercial fishing was once a major industry but has been hurt by overfishing. After the war, between 1945 and 1954, the total annual catch increased and reached a maximum of 4,900 tonnes. However, unbalanced fishery led to the drastic decrease of catch in 1955–1963, sometimes to 1,600 tonnes per year. Trawling has been forbidden in Lake Ladoga since 1956 and some other restrictions were imposed. The situation gradually recovered, and in 1971–1990

408-640: A total area of about 435 km . Ladoga is, on average, 5 m above sea level. Most of the islands, including the famous Valaam archipelago, Kilpola and Konevets , are situated in the northwest of the lake. Separated from the Baltic Sea by the Karelian Isthmus , it drains into the Gulf of Finland via the Neva River . Lake Ladoga is navigable, being a part of the Volga–Baltic Waterway connecting

476-463: 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

544-500: 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

612-683: 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

680-552: 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

748-586: Is known, hosts Jotnian sediments . During the Pleistocene glaciations the depression was partially stripped of its sedimentary rock fill by glacial overdeepening . During the Last Glacial Maximum , about 17,000 years BP , the lake served likely as a channel that concentrated ice of the Fennoscandian Ice Sheet into an ice stream that fed glacier lobes further east. Deglaciation following

816-400: Is mentioned, a clear link to the Neva River and possibly further to Finnish nevo 'sea' or neva 'bog, quagmire'. Ancient Norse sagas and Hanseatic treaties both mention a city made of lakes named Old Norse Aldeigja or Aldoga . Since the beginning of the 14th century this hydronym was commonly known as Ladoga . According to T. N. Jackson, it can be taken "almost for granted that

884-478: 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

952-601: The Baltic Sea with the Volga River . The Ladoga Canal bypasses the lake in the south, connecting the Neva to the Svir . The basin of Lake Ladoga includes about 50,000 lakes and 3,500 rivers longer than 10 km. About 85% of the water inflow is due to tributaries, 13% is due to precipitation , and 2% is due to underground waters. Geologically, the Lake Ladoga depression is a graben and syncline structure of Proterozoic age ( Precambrian ). This "Ladoga–Pasha structure", as it

1020-513: 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 ,

1088-713: The Ingrian War , a fraction of the Ladoga coast was occupied by Sweden. In 1617, by the Treaty of Stolbovo , the northern and western coast was ceded by Russia to Sweden. In 1721, after the Great Northern War , it was restitutioned to Russia by the Treaty of Nystad . In the 18th century, the Ladoga Canal was built to bypass the lake which was prone to winds and storms that destroyed hundreds of cargo ships. Later, from around 1812–1940

1156-620: 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

1224-702: 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

1292-505: 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

1360-554: 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

1428-574: The Weichselian glaciation took place in the Lake Ladoga basin between 12,500 and 11,500 radiocarbon years BP . Lake Ladoga was initially part of the Baltic Ice Lake (70–80 m. above present sea level ), a historical freshwater stage of Baltic Sea . It is possible, though not certain, that Ladoga was isolated from it during regression of the subsequent Yoldia Sea brackish stage (10,200–9,500 BP). The isolation threshold should be at Heinjoki to

1496-505: 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,

1564-585: 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

1632-509: 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

1700-596: 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

1768-681: 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

1836-553: 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

1904-561: The Neva River, barely missing some of its bridges and an 1898-built steam tugboat . The tugboat rushed to the plane and towed it to the shore. The plane's pilot was at first fired from his job but was later reinstated and awarded the Order of the Red Star . Lake Ladoga Lake Ladoga is a freshwater lake located in the Republic of Karelia and Leningrad Oblast in northwestern Russia , in

1972-410: 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

2040-441: 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

2108-408: The Russian dialectal word алодь, meaning 'open lake, extensive water field'. Eugene Helimski by contrast, offers an etymology rooted in German. In his opinion, the primary name of the lake was Old Norse : * Aldauga 'old source', associated to the open sea, in contrast to the name of the Neva River (flowing from Lake Ladoga) which would derive from the German expression for 'the new'. Through

2176-698: The Slavic population and transformed by means of the Old East Slavic metathesis ald- → lad- to Old East Slavic : Ладога . The Old Norse intermediary word between Finnish and Old East Slavic word is fully supported by archeology, since the Scandinavians first appeared in Ladoga in the early 750s, that is, a couple of decades before the Slavs . Other hypotheses about the origin of the name derive it from Karelian : aalto 'wave' and Karelian : aaltokas 'wavy', or from

2244-547: The Soviet Union. During World War II not only Finnish and Soviet, but also German and Italian vessels operated there (see also Naval Detachment K and Regia Marina ). Under these circumstances, during much of the Siege of Leningrad (1941–44), Lake Ladoga provided the only access to the besieged city as a section of the eastern shore remained in Soviet hands. Supplies were transported into Leningrad with trucks on winter roads over

2312-546: 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,

2380-464: The catch ranged between 4,900 and 6,900 tonnes per year, about the same level as the total catch in 1938. Fish farms and recreational fishing are developing. It has its own endemic ringed seal subspecies known as the Ladoga seal . Since the beginning of the 1960s Ladoga has become considerably eutrophicated . Nizhnesvirsky Natural Reserve is situated along the shore of Lake Ladoga immediately to

2448-582: 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

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

2584-565: 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

2652-585: 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

2720-747: The course of the Swedish–Novgorodian Wars , the area was disputed between the Novgorod Republic and Sweden. In the early 14th century, the fortresses of Korela (Kexholm) and Oreshek (Nöteborg) were established along the banks of the lake. During the Russo-Swedish War of 1656–1658, the Swedes deployed several armed vessels (called Lodja) on lake Ladoga to combat the Russians though no large sea battles were fought. The ancient Valaam Monastery

2788-584: 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

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

2924-420: The diversity of fish species in Neva is small. Permanent residents include such undemanding to environment species as perch , ruffe and roaches . Many fish species are transitory, of which commercial value have smelt , vendace and partly salmon . Floods in St. Petersburg are usually caused by the overflow of the delta of Neva and by surging water in the eastern part of Neva Bay . They are registered when

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

3060-563: The east of Vyborg , where the Baltic Sea and Ladoga were connected by a strait or a river outlet at least until the formation of the River Neva, and possibly even much later, until the 12th century AD or so. At 9,500 BP, Lake Onega , previously draining into the White Sea , started emptying into Ladoga via the River Svir . Between 9,500 and 9,100 BP, during the transgression of Ancylus Lake ,

3128-556: 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,

3196-525: The intermediate form *Aldaugja , Old Norse : Aldeigja came about, referring to the city of Ladoga. The lake has an average surface area of 17,891 km (excluding the islands), slightly larger than Kuwait . Its north-to-south length is 219 km and its average width is 83 km; the average depth is 47 m, although it reaches a maximum of 230 m in the north-western part. Basin area: 276,000 km , volume: 837 km (earlier estimated as 908 km ). There are around 660 islands, with

3264-524: The lake was shared between Finland and Russia. According to the conditions of the 1920 Tartu Peace Treaty militarization of the lake was severely restricted. However, both Soviet Russia and Finland had flotillas in Ladoga (see also Finnish Ladoga Naval Detachment ). After the Winter War (1939–40) according to the Moscow Peace Treaty , Ladoga, previously shared with Finland, became an internal basin of

3332-729: 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

3400-406: 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,

3468-569: The lower portions of Izhora River , then a tributary of the Gulf of Finland , between 4,000 and 2,000 BP. Dating of some sediments in the northwestern part of Lake Ladoga suggests it happened at 3,100 radiocarbon years BP (3,410–3,250 calendar years BP). The Ladoga is rich with fish. 48 forms (species and infra specific taxa) of fish have been encountered in the lake, including roach , carp bream , zander , European perch , ruffe , endemic variety of smelt , two varieties of Coregonus albula (vendace), eight varieties of Coregonus lavaretus ,

3536-450: 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

3604-522: 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

3672-464: The name of Ladoga first referred to the river, then the city, and only then the lake". Therefore, he considers the primary hydronym Ladoga to originate in the eponymous inflow to the lower reaches of the Volkhov River whose early Finnic name was Alodejoki (corresponding to modern Finnish : Alojen joki ) 'river of the lowlands'. The Germanic toponym ( Aldeigja ~ Aldoga ) was soon borrowed by

3740-502: The next brackish-water stage of the Baltic, occasionally invaded Ladoga between 7,000 and 5,000 BP. Around 5,000 BP the waters of the Saimaa Lake penetrated Salpausselkä and formed a new outlet, River Vuoksi , entering Lake Ladoga in the northwestern corner and raising its level by 1–2 m. The River Neva originated when the Ladoga waters at last broke through the threshold at Porogi into

3808-564: The next freshwater stage of the Baltic, Ladoga certainly became part of it, even if they hadn't been connected immediately before. During the Ancylus Lake subsequent regression, around 8,800 BP Ladoga became isolated. Ladoga slowly transgressed in its southern part due to uplift of the Baltic Shield in the north. It has been hypothesized, but not proven, that waters of the Litorina Sea ,

3876-414: The north of the mouth of the River Svir . The Ladoga has a population of Arctic char that is genetically close to the chars of Lake Sommen and Lake Vättern in southern Sweden. In the Middle Ages , the lake formed a vital part of the trade route from the Varangians to the Eastern Roman Empire , with the Norse emporium at Staraya Ladoga defending the mouth of the Volkhov since the 8th century. In

3944-405: 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)

4012-423: 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

4080-514: 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

4148-454: 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

It is the largest lake located entirely in Europe, the second largest lake in Russia after Lake Baikal , and the 14th largest freshwater lake by area in the world. It is comparable in size to Lake Ontario . Ladoga Lacus , a methane lake on Saturn 's moon Titan , is named after the lake. In one of Nestor's chronicles from the 12th century a lake called "the Great Nevo"

4284-420: The water rises above 160 centimetres (63 in) with respect to a gauge at the Mining Institute . More than 300 floods occurred after the city was founded in 1703. Three of them were catastrophic: on 7 November 1824, when water rose to 421 centimetres (166 in); on 23 September 1924 when it reached 369 centimetres (145 in), and 10 September 1777 when it rose to 321 centimetres (126 in). However,
