White Lake is one of the largest lakes on the Dniester estuary after Lakes Tudorovo and Putryne. The number of white lilies on the lake is so great that its surface seems white. The lake is about 2 km long, 1.3 km wide. In some places it is up to 1.6 m deep. The lake is connected with the Dniester and Turunchuk by channels. The total number of plant species is only about 25 species, but, nevertheless, it is a unique habitat of plant species, protected at different environmental levels.
