Study of the diversity and structure of communities of invertebrate hydrobionts for the assessment of the ecological state of the ecosystems of the Navaria reservoir and its tributaries in the Lviv district of the Lviv region.

The results of studies of benthos and periphyton in the water area of the Navaria reservoir and its tributary are presented. The headwaters of the Shchyrka are located in a forest massif, but a large pond has been created on its border (the village of Basivka), which is fenced off without access, although the pond itself is flowing, which contradicts the current legislation on the privatization of flowing water bodies. The water regime of Shchyrka depends on the flow regime of this pond. Also, the riverbed is partially used as a channelized outlet for household water discharges. It is necessary to carry out cleaning and formation of the channel to increase the flow of water that will enter the reservoir, as well as to regulate water discharges from the pond in the village. Basivka
The Malechkovycha River is practically a sewage channel for the settlements of Malechkovychy, Nagoryany, Solonka. Similarly, channel cleaning works and sewerage of settlements in the basin are necessary.
14 hydroecological plankton samples were taken from ten stations of the Navaria reservoir. Plankton sampling stations covered all the main biotopes of the reservoir. A total of 17 benthos and periphyton samples were taken. The samples were common to these two ecological groups of hydrobionts. Sampling was carried out in the water area of the Navaria reservoir, as well as in the channels of its tributaries - Shchyrka, Malechkovycha and Kovyr.
According to the preliminary analysis, the main problems of the ecological state of the reservoir are the state of its tributaries - Shchyrka and Malechkovich.
Without solving the ecological situation in the inflows of the reservoir, any works in its bed will have a temporary positive character.
