Lake Senga was formed at the confluence of two rivers, Senga and Malaya Senga, and compared to other Senezh lakes, it is quite deep, reaching a depth of 28 meters.
On the northern shore is the tourist center of the hunting farm "Dynamo", and on the southern shore is the picturesque tract of Seng-Ozero, located on the site of an ancient village.
In 1970, archaeologists discovered a site of an ancient man of the Neolithic era on the shore of Seng-Ozero. During excavations, they found flint chips, pieces of ceramics, a scraper, an arrowhead, arrows, knives, and stone jewelry.
There is a legend that in the 17th century, a wooden church of St. Nicholas the Wonderworker stood on the shore of the lake, but in the spring of 1638, this church sank into the water.
