Description
A calm, flat river, heavily regulated by dams, navigable in places from Tambov itself. The list of inland waterways in Russia includes a section from the mouth to the village of Tenshupino with a length of 47 km. The left bank is treeless, heavily populated, but the villages are mostly 1–3 km from the river. Along the right bank almost everywhere there is a forest belt, but it comes to the water only in certain places, as it was cut down during the Great Patriotic War. On the bank of the Tsna River there is the Holy Spring, known in Tambov and the nearest regions, located in the village of Treguliai. In the summer, many people come there to drink from the spring or bathe. The price below Tambov is a meandering calm river, 40–80 m wide, flowing along a wide valley with a lot of creeks, old men, a stream where you can go fishing. On the banks of the reeds, thickets of bush. Water is markedly polluted. From Tambov to Morshansk there are 5 dams with locks. The first - in the village of Tambov Forestry. The second one is near the village of Goreloe. Behind her, the river makes a long loop. Near the village of Troitskaya Dubrava is the third gateway. Behind the village of Kuleshovo is an oak forest. The forest comes to the shore and near the village of Perkino. In the city of Tambov in 1912 was built the first in the Tambov region a small hydroelectric station. Below Perkino begins the Semikinskiy Canal, which significantly shortens the way for Tsna. In the floodplain of Tsna near Perkino, Semikino and below - the labyrinths of overgrown with old reeds. Below the village of Semikino - Lake Lebyazhye and Orekhov Zaton - the largest floodplain lakes on the river Tsne. Below the Lake Orekhov Zaton on the high right bank is a natural species platform, from where the panorama of the village of Kulevatovo, the floodplain of the Tsna River, the mouth of the Chelnovoi River comes off. The fourth dam is behind the village of Mamontovo, the fifth - in Morshansk. Below Morshansk, Tsna becomes wider, the current is faster, beaches with small, sometimes silty, sand appear. The beaches are mainly meadow, only near Mutasievo on the right bank of the wedge is the forest to which the creek leads. Before the village Serpovoe - the sixth dam. Ten kilometers from the dam after the mouth of the Serp tributary on the right high bank is a pine forest. At local residents this tract is called the Serpovsky Utesom. Pine forest, reaching the river, there is also in front of the Rysly; Behind the village there is a floating bridge. The village of Chernitovo is a dam. Behind the dam on the banks again meadows. The river becomes wide. Before the last dam, the river forms a reservoir with a length of about 6 km and a width of 0.5 km. The dam is also in the area of the villages Aglomazovo and Tenshupino, where the river spills about 1 km. But after the reconstruction of the dam, the dam began to collapse year after year, and now the river has become much shallow. Below the dam, the channel of the Tznu is narrowed to 40–50 m, the current accelerates, sandy rifts appear. The forest approaches the water in the form of separate islands. In Soviet times, the river was used for navigation, along the entire length of the shipping section from Tambov. For passenger navigation, air-cushion ships of the Zarnitsa type were used. Widely used by tourists for rafting.
