Tsna River (Moksha basin) mouth to the village of Tenshupino with a length of 47 km (2002). 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.
