Abstract
Lakes are one of the main storage of freshwater. Such ecosystems are exposed to strong anthropogenic influence, especially in areas of intensive agriculture and industrial development. Regular monitoring of individual biogenic or abiogenic factors does not always allow an adequate assessment of theecological state of the reservoir. Therefore, the search for and introduction of new methods for assessingthe ecological status of natural objects remains highly relevant. One of the such methods for assessingthe ecological state of an ecosystem is a comprehensive study of the biodiversity of viruses, which are Lakes are one of the main storage of freshwater.
