The Vychegda in Koryazhma is navigable, and in summer there is regular passenger navigation connecting Kotlas and Soyga (located approximately half-way between Koryazhma and Yarensk).
The combined stream, now called the Northern Dvina, flows north about 60 km and receives the west-flowing Vychegda at Kotlas and then turns northwest to flow into the White Sea.
They passed a little river called Kirtza, near Ozomoys (or Gzomoys), came to Veuslima (?) on the river Witzogda (Vychegda), running into the Dwina, then they stayed in Lawrenskoy ( 3–7 July 1704; possibly Yarensk, known as Yerenskoy Gorodok at that time).
