This paper reports the results of a long-term research related to water quality, trophic status and phytoplankton species composition of major lentic water bodies in northeastern Turkey. Phytoplankton of studied water bodies consisted of 253 taxa from 79 genera belonging to Bacillariophyta, Chlorophyta, Cyanophyta, Euglenophyta, Dinophyta, and Chrysophyta. Bacillariophyta were generally dominant in the phytoplankton community of studied water bodies. Seasonal development of phytoplankton exhibited two peaks: one in late spring and the other one in autumn. The trophic status and water quality properties of the studied water bodies are discussed in detail in the text.

This paper presents the results of a long-term research regarding the species diversity and composition of benthic algae in major bentic water bodies of the northeastern region of Turkey. The presented data cover identified 344 taxa with their occurrence. Bacillariophyta was the most numerous group with the highest number of species (215) followed by Chlorophyta (83), Cyanophyta (28), Euglenophyta (16), and Dianophyta (2). The taxonomic composition of the benthic algal flora was analyzed. The diatom taxa that grow well in slightly alkaline waters were found to be abundant in the benthic algal community.
