The article is dedicated to the problem of artificial
Lake Sasyk which was transformed from a salty water estuary
into a freshwater reservoir at the expense of the Danube
waters.
In the first decades, the irrigative water conditions were not
achieved due to the arrival of salts from the bottom sediments.
Currently, the water quality formation process in Lake Sasyk
has stabilized, but the problem of land irrigation remains urgent.
The article gives an irrigation assessment of the quality of the
Sasyk reservoir according to various methods considering
observations in the HPS-2 region from 2007 to 2017. A
detailed typification of irrigation waters based on Alekin O. A.
water typing is proposed.
It was found that mineralization and the content of sodium and
magnesium ions in the Sasyk waters promote salinization and
alkalinization of soils. For the safe use of this water for
irrigation, both chemical reclamation and dilution with water
are necessary.
