We study the rivers of the Leningrad region: Narva, Luga, Dolgaya, Svir, Okhta

Almost all the rivers of the Leningrad region belong to the Baltic Sea basin. It follows that they carry their waters to the Atlantic Ocean. And only the water system, located in the extreme eastern part, belongs to the Volga Basin.

The dense river network in this area is well developed. If you add the length of all the water flows of this region, you will get a fairly large figure, just over 50 thousand km. The rivers of the Leningrad Region are mainly fed by snow and precipitation. Characterized by spring flood and winter steady low water. The whole water system of the region is quite branched.

The Luga River

The Luga River begins in the Novgorod region near the village of Tesovsky at an altitude of 53 meters and carries its waters to the Luga Bay in the Gulf of Finland. The length of the water flow is slightly more than 350 km, and the catchment area is about 13 thousand square meters. Km. The Luga River of the Leningrad Region is a watercourse with a large number of tributaries, but it is customary to single out only the six largest ones: Long, Saba - left, and Oredezh, Lizard, Lemovzha, Vruba - right.

The river bed is mostly sandy, but on the moraine hills pebble, as there are rapids (Kingiseppsky and Sobsky). The floodplain of the Meadow is not very rugged, in places the old men and bays meet. The ice is covered in December, it is opened in April.

The rivers of the Leningrad Region are of great importance for the region. For example, p. Meadow is used in shipping, but only in certain areas between the rapids. It is also involved in the city's water supply system and in the energy sector (currently the power plant is conserved). The ecological situation is satisfactory.

The long river (Leningrad region)

The Dolgaya River is the left tributary of the river. Luga, flows only in Russia (the Leningrad Region). Its source is a small Spass-Kotorskoe lake. Further downstream there are many reservoirs, of which the Long eats. Its waters it carries to the river Luga. The length of the Dolgoy River is slightly more than 90 km, and the area of the basin is 830 sq. Km. Km. The water flow has tributaries: Dymakarka (left) and Samro (right).

The Narva River

Narva (another name - Narva or Beck) is the Estonian-Russian border river. It starts from Lake Chudsko-Pskovskaya at a height of 30 meters above sea level and carries its waters to the Narva Bay in the Gulf of Finland. The length of the river is only 77 km, with a depth of up to five and a half meters, and the average width is about 250 m, the catchment area is 56 200 sq. Km. Km. On this water stream there are two major thresholds, which are 17 km from the mouth, on which the eponymous city is built. There is also a water reservoir mirror. The Narva River freezes in December, the ice keeps till April.

There are quite a few tributaries near the watercourse, but Rossony and Plussa are considered to be the main ones. At the first, an interesting phenomenon is observed, which was called the "inversion" for what is a binder between r. Luga and the river. Narva. The peculiarity lies in the fact that Rosson, depending on the water level, can change the flow direction in one direction, then the other.

Narva plays an important role in providing two countries: small shipping, there are hydroelectric power stations, recreational value, and also economic. The border river is rich in roach, pike, rudd, perch and bream.

The Svir River

The list of "Rivers of the Leningrad Region" is supplemented by a large watercourse - Svir. It is the most important link in the Mariinsky water system, now the Volga-Baltic waterway. The river originates from Onega Lake and for 224 km carries water to Ladoga, forming a delta. The drainage basin is more than 84 thousand square meters. Km. The width of the river varies from 100 meters to 12 kilometers in high water.

Svir has a lot of left tributaries, but the right is much smaller. This phenomenon is explained by the asymmetry of the basin. The largest left tributaries are Pasha and Oyat. The river flows through the hilly terrain where the glaciers passed, and therefore is not without rapids. But anthropogenic change in the channel raised the water level and completely flooded them. The river Svir is used for the purposes of hydroelectric power supply, navigation, rafting, recreation and fishing. In the river there is salmon, grayling, catfish, ide.

Okhta River

The right major inflow of the Neva River is the Okhta River ("Bear"). The source is in the Lembolovo heights of the Vsevolozhsk district. The length of the river is 90 km, and the width varies from 10 to 60 m, the depth is no more than 6 m. The channel of the Okhta is deeply incised, slightly curved, the floodplain is lake, the banks are steep (slope up to 5 m), the bottom is muddy and level. There are many tributaries: Kharvazi, Pippolovka, Okkervil, etc. The ecological situation on the river is negative, and in 2011 it was given the 4th level - "dirty".
