ABSTRACT
Increasingly relevant issues of our time are high fluctuations in climate, which have
adverse impacts on a water balance in landscape. Distribution of precipitation is shifted on the border of drought and a spate. These abnormalities are most evident on small streams where are a cause of fatal consequences for a lot of population and species of aquatic animal. The use of macroinvertebrates as a group of organisms for assess the effects of drought is particularly advantageous for the reason that these indication species are present in large quantities. Also, different regulation of water flows brings different spatial variability and the possibility of overcoming natural disasters. It is also important to take into account the possible overlap impact of anthropogenic factors above drought. At the evaluation the situation of the drought has been used three-year monitoring Trusovice stream. It was research on 13-km section of the stream, which different ground and anthropogenic pollution. The research was held during status of flooding and the drought. It pointed the different abilities and resilience of different kinds of macroinvertebrates, which are one of the cornerstones in the revival of flow.
