The Klyazma (Russian Клязьма ) is a river in Russia. It is a left tributary of the Oka, which in turn flows into the Volga.
The 686 km long Klyazma springs north of Moscow in the Moscow ridge in the Moscow Oblast. They first flows in a southerly direction until it reaches the Northern Administrative District of Moscow south of the airport Sheremetyevo. Here she turns to the east and forms for a few miles, the boundary between the city of Moscow and the Oblast same name.
Then the Klyazma reached the 1937 -built reservoir Kljasminskoje, which serves the power generation and as a recreational area. Shortly after Schtscholkowo it flows through the northern part of Losiny Park. From here it forms the northern boundary of the Meschtschora low level.
Slightly above Lossino - Petrovsky turns the Klyazma in southeastern direction. It flows through Noginsk, Pavlovsky Posad and Orechowo - Zuyevo, from where it flows back into predominantly easterly and north-easterly direction. Only a little less than Orechowo - Zuyevo it reaches the west of Vladimir Oblast. Here the Pekscha opens from the left in the river. Subsequently, the course of the river Klyazma temporarily forms a natural border between Moscow and Vladimir oblasts.
Before Sobinka the river turns to the northeast, the Polya absorbs from the right and then flows through the central part of Vladimir Oblast. A little later they reached the regional capital Vladimir. Below the town the Nerl from the left and the right of a Sudogda lead. Shortly after Kovrov after it has received the Uwod from the left, the Klyazma makes for some miles up the border with Ivanovo, but turns again to the southeast and flows through the north-east of Vladimir Oblast.
Shortly after Gorokhovets, in the extreme east of Vladimir Oblast, the Klyazma finally reaches the Nizhny Novgorod Oblast, where it joins after a few kilometers towards Gorbatov from the left in the Oka.
The Klyazma is strongly wound on her entire life and has many backwaters.
The area of the Klyazma has been inhabited since Neolithic times. Later, since the 1st millennium BC, settled here Finno-Ugric tribes such as the Merja, Muroma and Meschtscheren. In the Middle Ages, the area came under Slavic influence.
With the rise of the Principality of Vladimir - Suzdal in the 11th and 12th century, the importance of Klyazma increased as transport and trade. 1108 founded the Kievan Grand Prince Vladimir Monomakh, the city of Vladimir on the Klyazma. Until 1238, when Vladimir was conquered during the Mongol invasion of Russia under Batu Khan, Vladimir - Suzdal experienced a period of prosperity. After the end of Mongol rule was the region regain its former importance not again and fell in the early 14th century under influence of the emerging countries the Grand Duchy of Moscow.
At the Klyazma since historical times, the river fishing an important source of income. The river was also always been an important transport route. In Soviet times it was navigable for 302 km length from the mouth to, but this is only to 120 km and on the reservoir Kljasminskoje the case.
The river is dammed to several reservoirs serving the power generation. Especially in the vicinity of Moscow, these also play an important role for recreation, such as for fishing and canoeing.
Although the Klyazma is still heavily polluted at its upper reaches, there is a variety of animal and plant species in and around the river. Fish such as bream, nose, perch, pike, burbot, gudgeon and chub are found in large numbers. Although still very common in the 19th century, catfish and starlet, however, are hard to find.
