The lake's waters contain relatively little salt (about 4-11‰). Lake Burgas is inhabited by a wide variety of species, including 23 fish, 60 invertebrates and 254 bird species (of which 61 are endangered in Bulgaria and 9 in the world).

An important fish-producing reservoir in the past, Lake Burgas lost much of its economic importance after the construction of the petrochemical plant near the city, but has witnessed an increasing number of species and decreasing pollution in recent years.
