Currently, the water level in the Kazanka River is 50.2 meters according to the Baltic system.
Bortyakov recalled that similar phenomena had already been observed in 2010 and 2019, which led to massive fish deaths.
“The supply of fresh water to the winter pits stops, which interferes with the access of oxygen. This leads to direct harm,” he explained.
In addition, a decrease in the area of the reservoir complicates the processes of natural water purification, which leads to a deterioration in its quality. This affects not only fish, but also plankton and bottom organisms.
“There will likely be widespread mortality in the backwaters, especially in the shallower parts of the reservoir,” he added.
Throughout the year, environmentalists and social activists in Tatarstan have been sounding the alarm about the water level in the rivers of the republic. All water from the reservoir is sent to the lower regions of the country, which leads to problems in the upper regions, reports inkazan.ru.
