Description
The river flows from the swamp s. Zaozerye of the Uglich region . Initially, it flows eastward along the territory of modern Borisoglebsky and Rostov regions . Near the village of Semibratovo, it abruptly turns south and around s. Nikolo-Perevoz merges with the river. Vyoksoy , forming the Kotorosl River.
The width of the channel varies from 10 to 40 m, the depth from 0.2 to 2 m. [2] The Ustye River in its course crosses several geomorphological regions, as if descending from the overlying high-level steps to the lower ones. This explains the rapid course and the whimsical nature of the wandering of the channel, which is continuously bent, often branching into sleeves and forming middle and floodplain islands.
Along the banks - on the terraces and the hills of the river, ripe dry (white-moss, lichen and heather ) picturesque pine trees have been preserved.
The river has five main tributaries, with a length of more than 20 km, these are: p. Lut - 20 km, p. Mogza - 84 km, p. Shula - 25 km, river League - 31 km, p. Ilma - 32 km. Ten tributaries with a length of 10 to 20 km are Naritsa , Pura , Lehta , Laskovka , Derinochka , Talitsa , Zvenich , Inbozhka , Gorda , Bolzhbin and about 42 tributaries of less than 10 km. [2]
On the river there are urban settlements Borisoglebsky and Semibratovo .
