The presented paper contains the results of preliminary studies, which were suppose to verify whether forming in reservoirs algal mats may transport the diaspores and carpological remains plants and sig-nificantly influence formation of taphocenosis. The study was conducted in 2012 in a small reservoir created in a sand pit "Siemonia". In studied reservoir was found a formation of two types of algae mats: built mainly by filamentous algae or diatoms. In both cases, it proved that the scale identified in the studied reservoir transport of diaspores and redepo-sition of carpological remains with the participation of algal mats suggests that the possibility of their appearance should be taken into account in the interpretation of the macrofossil analysis.
