Situated in the Tver region in Russia, Lake Brosno is a place of mystery and intrigue. From legends of giant snakes or dragons living in the water to underwater volcanoes, stories surrounding the happenings in the Lake abound. The lake has a depth of about 43 meters at its deepest point. Lake Brosno also has many other things of interest. There is a Sunken church on the western part of the lake, as well as many fish species which seem to be characteristically out of place in this large body of water, such as burbot and perch which are saltwater fish.
