 Nowadays both the bay and the inlet are filled with Caspian Sea water.The water in the shallow inlet has striking colours, in which delicate tones of blue or of brown predominate according to the seasons.The area was mapped by Fedor Ivanovich Soimonov during the Caspian Expedition, which surveyed the Caspian Sea from 1719 to 1727, but was only accurately described later by G. S. Karelin in 1832.
