The Dnieper rapids were flooded with the water of a storage basin only in 1927. By that time this stone barrier on the way to the Black Sea played a key part in navigation, trade, settling by the river, appearance of new useful arts as well as various kinds of activity. The first rapids could be found near the present day village Starye Kodaki – and were called Kodak rapids. As it was difficult to navigate through this section of the Dnieper, a new speciality of a pilot appeared. The former pilots’ settlement has been preserved; and its name is Lotsmanskaya Kamenka and it is situated in the south-east part of the city.
