Dredging is planned to be carried out at the Volga-Caspian canal.
Some sectors of this shipping canal silt every year with annual spring floods.
In 2013, the sector between 123 km and 129 km saw a decrease of waterway depth from nominal 4.5 m to 4 m and even 3.5 m.
Experts note the annual character of the problem. They attribute the current critical situation to a heavy flood which ended in the Astrakhan region last week.
The flood brought much silt and the canal depth decreased considerably.
