Drift is a major feature in the continuous distribution of macroinvertebrates. In the currentstudy, the density and variety of mites that float in the spring-fed stream Heval are observed andevaluated. During the evaluation period from December 2021 to February 2022, a maximumof 15 species from six families were recorded. The Dobriyal-Bahuguna Drifting Index (DBDI)gives insight into the relationship between the population that is in the environment at a giventime and the population that chooses to drift or is forced to drift. The findings of DBDI revealedthat the maximum drifting value (0.2886) for all mite populations was observed in February inthe spring-fed stream Heval. In contrast, it was at its lowest (0.2513) in December
