The river begins its way 2 km to the north from the village Cityino. It flows through 7 lakes (including Negra, Vyshadskoe, Myadesno, Tiosto).
The main tributaries are Osecha (on the right), Jordan and Solonovka (on the left). It flows into Uswiesch near the village of Luban Uswiechy district of the Pskov region(the Russian Federation). The valley to the village Smolovka is box-shaped or trapezoidal, with a width of 300-400 m. Its downstream is inexpressive. Floodplain double-sided with a width of 100-300 m. The bed is moderately winding with a width of 4-6 m, in the middle and lower reaches in places up to 50 m.
From Lake Vyshedsky it is recommended to walk only on high water, for there are many obstacles. In summer it is recommended to go from Smolovka. The most interesting place of the river is difficult to determine because the river for a multi-day hike represents a diversity of perceptions of each day of the trip: from tranquility with blockages to tumultuous rifts in Verechye and Zarechye, a «reed» course in the middle of the route, the beauty of lake Medesno and sailing on the Uvyacha. The site Vyshedskoe — Smolovka needs to be allocated more time.

- The length is 90 km.
- The water intake area is 598 km2.
