The Pjosa ( Russian Пёза ; also Pesa ) is a 363 km long right tributary of the Mesen in the northeast of the European part of Russia .
course
The Pjosa arises at a height of 61 m on the western flank of the northern Timan ridge from the Rotschuga coming from the right and the Bludnaja from the left. The several dozen kilometers long source rivers arise in the higher elevations of the Timan ridge at a good 200 m . The Pjosa flows in a westerly direction, strongly meandering in a wide valley, the extreme northeast of the mainland part of the Arkhangelsk Oblast . It flows into the Mesen above the village of Dorogorskoje at a height of only 4 m , a good 30 km southeast of the small town of the same name Mesen .
The most important tributaries are the Zjema , Tscheza and Nyafta from the left and the Loftura from the right. There are a large number of lakes in the river's catchment area.
Hydrography
The catchment area of the Pjosa covers 15,100 km². Near the mouth, the river is a good 250 meters wide and up to two meters deep; the flow velocity here is 0.3 m / s.
The Pjosa freezes from November to the first half of May. The water flow at the Igumnowo measuring point, 66 km above the mouth near the village of Bychye, is an annual average of 123 m³ / s with a minimum monthly mean of 20.3 m³ / s in March and a maximum monthly mean of 547 m³ / s in May as well as an absolute maximum of more than 2500 m³ / s.
Infrastructure
The Pjosa is navigable from Safonowo for 301 km when the water level is high.
There are no cities along the river, but the rural settlements Safonowo, Mossejewo and Bytschje with a number of districts. The towns on the upper and middle reaches can only be reached by water in summer and via an ice road on the Pjosa in winter, as there are no roads in the area that can be used all year round - except for Bychye. The road that leads from the city of Mesen up the right bank of the Mesen River to the mouth of its largest tributary, the Vaschka near Leschukonskoje , crosses the Pjosa not far from its mouth by means of a car ferry .
