Scheme of the river.

The river has a glacial origin. Initially, it was a stream up to three meters wide, after the construction of the dam on Petritsa and the dam on the Rozai itself two ponds were formed. Several more ponds are located in the area of Sertyakino village and Tyatino village. Now all ponds are drying up and overgrown. In areas that were covered with water twenty years ago, trees that are up to 4 meters high have now grown.

In the 80s of the 20th century, vegetable gardens began to appear on the site where the wider part of the river flows into the stream. Potatoes , rye , berries and other crops were grown on the banks. The gardens were fenced with fences collected from scrap materials, and on the plots there were small sheds . All the gardens had access to the stream. The first sheds are not preserved, areas are overgrown, but later gardens are still used (sections behind the bridge and to the village of Sertyakino ). From the village Sertyakino to SNT "Polyanka" the river flows through the field, but trees grow on the banks of the river. In the past 15 years, numerous cottages have been built on the north shore of the wide part of Sosnovka.
