The trophic state and plankton distribution were investigated in a newly constructed reservoir (Feilaixia reservoir) in 2000. Being a throwflowing reservoir with a retention time of 15 days, its trophic state was high after inundation but decreased rapidly. During investigation, it was mesotrophic with low abundance of phytoplankton (0.39×106 cells·L-1) and zooplankton (52 ind·L-1). 29 species of phytoplankton and 53 species of zooplankton were observed in the reservoir. Cyanophyta and Chlorophyta predominated numerically in flood season and then Bacillariophyta in dry season. The abundance of zooplankton was a little higher in flood season than in dry season and predominated numerically by rotifer and nauplii. Although the trophic level in Feilaixia reservoir is a little high, it has low abundance of plankton for it's a throughflowing reservoir with high water runoff.
