Lake Adovo, located in the Gaynsky district (Komi-Permyak Okrug of Perm Krai) is the largest lake in the Komi area. It occupies the territory of 111 thousand hectares. The Adovo consists of two lakes: the Bolshoe (means ‘big’) and the Maloe (means ‘small’). The square of the water surface of the Bolshoe Adovo is 370 hectares, and the lake is 6 meters deep. The lakes are situated on the ancient lowland, on which the Kama used to flow to the Arctic Ocean in the Preglacial period.
There are several different versions about the name of the lake. According to the most popular one, the lake was created by the Devil, and so it was named the Adovo (formed of the noun ‘ad’, which means ‘hell’ in Russian). Linguists explain, that the name originated from the common Komi word ‘vad’, which means ‘rounded water pond’.
The lake is also notable for whooping swans’ nesting around there - these birds are very rare in Perm Krai.
