In mid-September 2015, we decided to visit the forest lake Deryabin. It is located in the Kama - Bakaldinskih bogs, ie the rivers and Kerzhents Vetluga. As usually happens in our campaigns, the main purpose is to check for the presence of the lake fish. We have done this successfully. There's a small poklёvyval okunёk. Just a hike we went 11.3 km. The lake held overnight. In the morning, I was able to see the magnificent sunrise.
